I have this Activity:
public class WelcomeActivity extends ActivityBase {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
setContentView(R.layout.welcome);
final OnClickListener Click = new OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(WelcomeActivity.this, WelcomeDoneActivity.class);
startActivityForResult(intent, 0);
setResult(RESULT_OK);
finish();
}
};
((TitleBar)findViewById(R.id.theTitleBar)).setOnClickCloseListener(Click);
}
And this test:
#Test
public void clickingLogin_shouldStartLoginActivity() {
WelcomeActivity activity = Robolectric.setupActivity(WelcomeActivity.class);
activity.findViewById(R.id.theTitleBar).performClick();
Intent expectedIntent = new Intent(activity, WelcomeDoneActivity.class);
assertThat(shadowOf(activity).getNextStartedActivity(), equalTo(expectedIntent));
}
how come I get an assertion error?
java.lang.AssertionError:
Expected: <Intent { cmp=com.w/.profile.WelcomeDoneActivity }>
but: was null
Update
I have tried this as well but the startedIntent == null
ShadowActivity shadowActivity = shadowOf(activity);
Intent startedIntent = shadowActivity.getNextStartedActivity();
// ShadowIntent shadowIntent = shadowOf(startedIntent);
// String name = startedIntent.getIntentClass().getName();
// assertThat(shadowIntent.getIntentClass().getName(), equalTo(targetActivityName));
Change:
shadowOf(activity).getNextStartedActivity()
To:
shadowOf(activity).getNextStartedActivityForResult()
In the code you posted, you are setting the onClick on the TitleBar via setOnClickCloseListener.
It looks like your TitleBar is a custom view, and the setOnClickCloseListener to me implies there is a 'close' button or view on the TitleBar that performClick() should be called on, not the TitleBar itself, in order for Robolectric to behave the way you expect.
It's hard to tell without knowing the TitleBar and setOnClickCloseListener implementation, but:
1) If you just want to click the TitleBar to launch the new activity,
then change setOnClickCloseListener to setOnClickListener,
Or
2) If the TitleBar contains a view of the close button/view (or whatever "ClickClose" refers to in setOnClickCloseListener!), delve into the TitleBar layout to find the ID of this view, and call performClick on that, it should resolve your issue.

I've been trying to find out the back navigation button to lead to another activity.
Every time when I pressed the back button, it goes to the previous activity which is not what I want. I would like to set the back button that goes to another activity I want, instead of previous one.
For example, I have Activity 1, 2 and 3. I was in Activity 2 and just moved to Activity 3. But when I press the back button, it goes automatically to the previous activity which is Activity 2. I want to make it to Activity 1 and not Activity 2. Can anyone suggest me a solution please?
You can make the button to go to a specific activity, instead of having the default behavior that you described.
It can be something like this:
#Override
public void onClick(View v) {
Intent intent = new Intent(Activity2.this, Activity3.class);
intent.putExtra("variable", information); //this is optional, but can be useful if you need to send a specific info to the next activity
startActivity(intent);
}
Activity 2 is parliamonar, and Activity 3 is federalparliamentary. I replaced parliamonar with Activity 1, but it still didn't solve the problem.
public class federalparliamentary extends AppCompatActivity {
Button federal;
private Object parliamonar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_federalparliamentary);
federal = findViewById(R.id.back160);
federal.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent reserve = new Intent(getApplicationContext(), parliamonar.class);
startActivity(reserve);
}
});
federal = findViewById(R.id.next164);
federal.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent reserve = new Intent(getApplicationContext(), sar.class);
startActivity(reserve);
}
});
}
public void onClick(View V) {
Intent back = new Intent((Context) parliamonar, federalparliamentary.class);
startActivity(back);
}
}
public class federalparliamentary extends AppCompatActivity {
Button federal;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_federalparliamentary);
federal = findViewById(R.id.back160);
federal.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent reserve = new Intent(getApplicationContext(), parliamonar.class);
startActivity(reserve);
}
});
federal = findViewById(R.id.next164);
federal.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent reserve = new Intent(getApplicationContext(), sar.class);
startActivity(reserve);
}
});
}
public void Onclick(View v) {
Intent intent = new Intent(federalparliamentary.this, politicalsystem.class);
startActivity(intent);
}
}
Activity 1 is "politicalsystem".
I added with #Override method, but it says that I have to remove the method, so I added outside, then it says that I have to extract interface, so clicked on it, then it gave me a bunch of list. So I chose onClick(v:View ):void, but it still didn't solve the issue. I tried in another way without #Override, but nothing changed when I tested my app. I also tried inside onCreate method which did not modified the navigation as I desired.
Is it possible to define the source of a click? I can access my MainActivity through either clicking on a RecyclerView or through a Notification action. Depending on which it is, I need to provide different info. Is there a way of saying: if click is from recyclerview then..., else if it is from notification action then...?
What I can think of so far is this, but the problem is I am not using buttons as such:
Button mClickButton1 = (Button)findViewById(R.id.clickButton1);
mClickButton1.setOnClickListener(this);
Button mClickButton2 = (Button)findViewById(R.id.clickButton2);
mClickButton2.setOnClickListener(this);
public void onClick(View v) {
switch (v.getId()) {
case R.id.clickButton1: {
// do something for button 1 click
break;
}
case R.id.clickButton2: {
// do something for button 2 click
break;
}
}
}
Thanks!
you have to define two different calling intents for the same activity and put info for each View Example :
mClickButton1.setOnClickListener(new onClickListener(){
public void onClick(View v) {
Intent view1_int = new Intent (this, MainActivity.class);
view1_int.putExtra("Calling Intent" ,"RecyclerView");
startaActivityForResult(view1_int);
}
});
mClickButton2.setOnClickListener(new onClickListener(){
public void onClick(View v) {
Intent view2_int = new Intent (this, MainActivity.class);
view1_int.putExtra("Calling Intent" ,"Notification action");
startaActivityForResult(view1_int);
}
});
and in the onCreate Method in your MainActivity you can say :
String callin_view;
callin_view =getresources.getIntent.getExtras("Calling_Intent");
This will retrieve the name of the calling source you defined
Further to my previous post, I now want to invoke a child activity from the main activity a number of times. In my real project (as opposed to the noddy test below), when the child activity is invoked, its header displays, "Enter first data set" then invites the user to enter some data. This data is actually stored in a common class rather than being returned to the main activity. Then the child needs to be called again with a new prompt "Enter second data set", and the same thing happens.
What I cannot work out is how to do this. If I include two calls to the child, every time, only the second call appears to happen, the prompt appearing in the child activity being "Enter second data set" every time. This startActivityForResult() method is I believe, designed to be used when you want to call an activity and wait for the result (which you do with an onActivityResult() do you not), but it does not wait.
How on earth do I do this? Sample code follows.
Thank you to anyone who can clearly explain where I'm going wrong and what the right code should be.
MainActivity code extract
#Override
public void onResume(){
super.onResume();
TextView maintop = (TextView)findViewById(R.id.maintop);
maintop.setText(Common.mess1);
}
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button mainbutton = (Button)findViewById(R.id.mainbutton);
mainbutton.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
Intent intent1 = new Intent(MainActivity.this,Child.class);
intent1.putExtra("Prompt", "Enter first data set");
startActivityForResult(intent1,1);
onActivityResult(1,1,intent1);
}
});
mainbutton.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
Intent intent2 = new Intent(MainActivity.this,Child.class);
intent2.putExtra("Prompt", "Enter second data set");
startActivityForResult(intent2,1);
onActivityResult(1,1,intent2);
}
});
}
You can only have one click listener in the button, so when you call set for the 2nd time it replaces the listener.
What you need to do is set the click listener for the enter first data, don't call to onActivityResult(1,1,intent1) that's not how you do it, you need override the method, and in onActivityResult call the 2nd.
Something like this:
static final int FIRST_INTENT = 1;
static final int SECOND_INTENT = 2;
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button mainbutton = (Button)findViewById(R.id.mainbutton);
mainbutton.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
Intent intent1 = new Intent(MainActivity.this,Child.class);
intent1.putExtra("Prompt", "Enter first data set");
startActivityForResult(intent1,FIRST_INTENT);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == FIRST_INTENT) {
if (resultCode == RESULT_OK) {
Intent intent2 = new Intent(MainActivity.this,Child.class);
intent2.putExtra("Prompt", "Enter second data set");
startActivityForResult(intent2,SECOND_INTENT);
}
}
}
And in your child activity
//DO SOMETHING
....
setResult(RESULT_OK)
finish();
}

Im brand new to android and I have no idea what I'm doing wrong. The current code looks like:
public class TypeActivity extends Activity {
private boolean alcoholin = false;
...
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.search_type);
alcohol = (Button) findViewById(R.id.alcohol_button);
...
alcohol.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
alcoholin=true;
Intent i = new Intent (TypeActivity.this,ingredients.class);
startActivity(i);
}
});
...
public boolean getalcholin(){
return alcoholin;
}
This code is then supposed to set a value in another class. I have tested the code and I know that if i state the the boolean is true in the beginning of my code, then I will make the other code's boolean equal true. However, if I try to set the value when the user presses the button the value does not get updated.
Please help!
On Android the standard way to send data from one Activity to another is by specifying "extras" on the Intent that you use to start a new activity.
You are already using an Intent in your onClick method to start your "ingredients" activity (Your code would be more readable if you named your activity something like IngredientsActivity instead) - you just need to add some "extras" to it.
Please read up on the training tutorial here, but without knowing what your ultimate goal is you probably want something like:
alcohol.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent (TypeActivity.this,IngredientsActivity.class);
i.putExtra(IngredientsActivity.EXTRA_INGREDIENT_TYPE, "alcohol");
startActivity(i);
}
});
... and then in IngredientsActivity you would have something like:
public static final String EXTRA_INGREDIENT_TYPE = "ingredient";
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ingredients);
String ingredientType = getIntent().getStringExtra(IngredientsActivity.EXTRA_INGREDIENT_TYPE);
}
This would never work because alcoholin would NOT exist as this is an entirely different Activity. Why don't you instead use the Extras of the intent to pass data between the two Activities.
Standards
Class names should always have each word capitalized like MyClassObject in java.
I am working on an android app that launches two activities using the on click listener everything in my code checks out fine except where the public void onClick(View v) begins I have multiple errors starting on that line and I am unable to run the code? I would kindly appreciate any help as I am fairly new to this. My code is as follows
public class Safaricom extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.safaricom);
Button button1 = (Button)findViewById(R.id.button1);
Button button2 = (Button)findViewById(R.id.button2);
button1.setOnClickListener(buttonClickListener);
button2.setOnClickListener(buttonClickListener);
}
private OnClickListener buttonClickListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = null;
switch(v.getId()){
case R.id.button1:
intent = new Intent(this, Second.class);
break;
case R.id.button2:
intent = new Intent(this, SignUp.class);
break;
}
if (intent != null)
this.startActivity(intent);
}
};
}
The Errors are at two points.
First where it says public void on click view ( The Error is - Multiple Markers at this line - implements android.view.View.OnClickListener.onClick- The method onClick(View) of type new View.OnClickListener(){} must override a superclass )
Second where it says this.startActivity(intent); (The Error is -The method startActivity(Intent) is undefined for the type new View.OnClickListener(){})
Instead of this use v.getContext() or YOUR_ACTIVITY.this
Actually If you read the Docs carefully, you will know that Intent parameters contain Activity so when you are using this it means that you are giving a parameter of type new View.OnClickListener
Well, I can see right off a couple of errors. To make it clearer since it apparently was not clear by simply looking at the code and learning. I added Safaricom.this in each of the new Intent statements. This is because the Intent constructor needs a Context as the first argument and an OnClickListener is not a Context, you need to ge the enclosing Activity which is a context. One other edit, I missed, the startActivity also needs to have Safaricom prepended.
public class Safaricom extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.safaricom);
Button button1 = (Button)findViewById(R.id.button1);
Button button2 = (Button)findViewById(R.id.button2);
button1.setOnClickListener(buttonClickListener);
button2.setOnClickListener(buttonClickListener);
}
private OnClickListener buttonClickListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = null;
switch(v.getId()){
case R.id.button1:
intent = new Intent(Safaricom.this, Second.class);
break;
case R.id.button2:
intent = new Intent(Safaricom.this, SignUp.class);
break;
}
if (intent != null)
Safaricom.this.startActivity(intent);
}
};
}
For the first error
The Error is - Multiple Markers at this line - implements android.view.View.OnClickListener.onClick- The method onClick(View) of type new View.OnClickListener(){} must override a superclass )
Try removing the #override
If that doesn't remove the second error then let us know if there is a different issue arising.
