Can't make an activity actually launch [duplicate]

Can't make an activity actually launch [duplicate] - java

Im trying to call a second activity from my Main Activity, using this code
Intent goToOrder = new Intent(ListOfOrdersActivity.this, OrderSummaryActivity.class);
startActivity(goToOrder);
Being my OrderSummaryActivity:
public class OrderSummaryActivity extends ActionBarActivity {
#Override
public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
super.onCreate(savedInstanceState, persistentState);
setContentView(R.layout.order_summary);
}
}
But the layout wont show on this activity, just a blank page.
This is the xml of the layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/name"
android:textSize="20sp"
android:textStyle="bold"
android:layout_margin="10dp"
/>
<TextView
android:id="#+id/order_resume_name"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/quantity"
android:textSize="20sp"
android:textStyle="bold"
android:layout_margin="10dp"/>
<TextView
android:id="#+id/order_resume_quantity"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/whipped_cream"
android:textSize="20sp"
android:textStyle="bold"
android:layout_margin="10dp"/>
<TextView
android:id="#+id/order_resume_whipped_cream"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/chocolate"
android:textSize="20sp"
android:textStyle="bold"
android:layout_margin="10dp"/>
<TextView
android:id="#+id/order_resume_chocolate"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/order_summary_total"
android:textSize="20sp"
android:textStyle="bold"
android:layout_margin="10dp"/>
<TextView
android:id="#+id/order_resume_total"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Any hint?

try overriding
public void onCreate(Bundle savedInstanceState)
instead of
public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState)

Try changing your OrderSummaryActivity.class to :
public class OrderSummaryActivity extends ActionBarActivity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.order_summary);
}
}

Thanks for taking time answering this. I am new in giving question here.

In your InputActivity
public class InputActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_input);
}
//Send data to HasilActivity.java
Intent intent = new Intent(this, HasilActivity.class);
// put your data here
intent.putExtra("value_one", editText.getText().toString().trim());
intent.putExtra("value_two", editText2.getText().toString().trim());
startActivity(intent)
}
and in your HasilActivity
public class HasilActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hasil);
String value = getIntent().getStringExtra("value_one");
String value2 = getIntent().getStringExtra("value_two");
}
}
that is :)

ViewHolder not show a button in method onSwiped()

I have a big issues about onSwiped method and set a button's visibility to VISIBLE. Here my code Java Class :
#Override
public void onSwiped(RecyclerView.ViewHolder viewHolder, int swipeDir) {
mRecyclerView.getAdapter();
StepListAdapter.ViewHolder listViewHolder = (StepListAdapter.ViewHolder) viewHolder;
listViewHolder.itemView.setBackgroundColor(mContext.getResources().getColor(R.color.accent));
listViewHolder.titleView.setVisibility(View.GONE);
listViewHolder.locationView.setVisibility(View.GONE);
listViewHolder.status.setVisibility(View.GONE);
listViewHolder.undoButton.setVisibility(View.VISIBLE);
listViewHolder.undoButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Do something
}
});
}
And here my xml layout file:
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="#+id/view"

android:layout_gravity="center"
android:padding="5sp"
android:textColor="#color/dark_grey"
android:layout_below="#id/step_title_text"
android:text="#string/empty"/>
<ImageView
android:id="#+id/status_image"
android:layout_width="26dp"
android:layout_height="26dp"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"/>
<Button
android:id="#+id/undo_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/undo"
android:textAllCaps="true"
android:visibility="gone"
android:textColor="#android:color/white"
android:layout_gravity="end|center_vertical"
android:layout_alignParentRight="true"
style="#style/Base.Widget.AppCompat.Button.Borderless"
/>
</RelativeLayout>
</android.support.v7.widget.CardView>
My problem is that when the method onSwiped was called, and after I setup the VISIBILITY of the button by Java code, the main card doesn't show the button .
Thanks a lot guys

Saving several EditText after program closes

I'm trying to make a Character sheet for a DnD like game. The point is to take user input and store it for future viewing and changing. Maybe I'm looking for a solution that doesn't exists but I want the EditTexts to stay the way they are if the user closes the app or just goes back to the title screen. Following is part of the xml file for the user input, the java file is basically blank

Java file
package com.example.mapuchii.gurps;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class Character_activity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_character_redo);
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
// Read values from the "savedInstanceState"-object and put them in your textview
}
#Override
protected void onSaveInstanceState(Bundle outState) {
// Save the values you need from your textview into "outState"-object
super.onSaveInstanceState(outState);
}
}

Here is one example:
public class Character_activity extends AppCompatActivity {
private EditText playerEditText;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_character_redo);
playerEditText = (EditText) findViewById(R.id.player);
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
playerEditText.setText(savedInstanceState.getString("SavedPlayer", "");
}
#Override
protected void onSaveInstanceState(Bundle outState) {
outState.putString("SavedPlayer", playerEditText.getText().toString());
super.onSaveInstanceState(outState);
}
}
This will save your text over an orientation change. If you want to save it when your process is killed then you need to look at SharedPreferences instead of a Bundle.

my java code for this layout:
public class Atherosclerosis extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.atherosclerosis);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.atherosclerosis, menu);
return true;
}
}

Use android:onClick="" and android:Clickable="true"
to make the Textview as a button

You can use OnClickListener on TextView and then use the following method on the OnClick, where textViewAbove is the TextView that is above the one you need to jump:
scrollView.post(
new Runnable() {
#Override
public void run() {
new CountDownTimer(1500, 20) {
#Override
public void onTick(long millisUntilFinished) {
scrollView.scrollTo(0, (int) (textViewAbove.getBottom()-millisUntilFinished));
}
#Override
public void onFinish() {
}
}.start();
}
}
);
Hope it helps!

You can have OnclickListener on TextView

Here is the code but still give me error till me where I am wrong?
public class Atherosclerosis extends Activity{
ScrollView scrollView;
TextView tvabove=(TextView)findViewById(R.id.pathophysiology_id);
#TargetApi(Build.VERSION_CODES.HONEYCOMB)
#SuppressLint("NewApi")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.atherosclerosis);
ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#6B8E23")));
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
TextView tv=(TextView)findViewById(R.id.Signandsymptompsid);
tv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
scrollView.post(
new Runnable() {
#Override
public void run() {
new CountDownTimer(1500, 20) {
#Override
public void onTick(long millisUntilFinished) {
scrollView.scrollTo(0, (int) (tvabove.getBottom()-millisUntilFinished));
}
#Override
public void onFinish() {
}
}.start();
}
}
);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.atherosclerosis, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Take appropriate action for each action item click
switch (item.getItemId()) {
case R.id.id_search:
Intent newActivity0 = new Intent(this,Search.class);
startActivity(newActivity0);
return true;
case R.id.id_favorit:
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}

We Keep Coding

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Can't make an activity actually launch [duplicate] - java

try overriding public void onCreate(Bundle savedInstanceState) instead of public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState)

Try changing your OrderSummaryActivity.class to : public class OrderSummaryActivity extends ActionBarActivity { #Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.order_summary); } }
