while I was testing my app using the virtual emulator (don't have a valid device where I can test), I found out a bug. That's the java.lang.StringIndexOutOfBoundsException: length=0; index=2 error, and it pops out when I click on an EditText and try to write in it. The EditText is set to appear when another button is clicked. Here is the XML:

You are getting error Because, You have set property 'textAllCaps' in EditText. This property is mostly used for TextView.
Remove This Property and try again.

I made the shopping cart app and I use the navigation drawer and in this navigation drawer I use the shopping cart icon.
Now, When i click on the particular item. It's open in new activity but its not showing the shopping cart icon, So how will it show? So,i see the item in the cart?
ItemDetailsActivity. java (This is the .java file of this image where i am unable to see the shopping cart icon, so i am unable to see how many items add in the cart)

I would like to ask on how to achieve to wrap a content in alertdialog?
Because the current output of my dialog has an excess white field.
Hope someone can help me to understand this problem thanks.

Here is some of my implementation in the MainActivity.java:
AlertDialog.Builder mBuilder = new AlertDialog.Builder(MainActivity.this);
View mView = getLayoutInflater().inflate(R.layout.activity_dialog, null);
.....
mBuilder.setView(mView);
final AlertDialog dialog = mBuilder.create();
dialog.show();
Try Creating a dialog like this. this works perfect and then right away your dialog logic is seperated from you activity logic
public class CustomDialog extends Dialog implements
android.view.View.OnClickListener {
public Activity c;
public CustomDialog d;
public Button yes, no;
public CustomDialog(Activity a) {
super(a);
// TODO Auto-generated constructor stub
this.c = a;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.dialog_layout);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//dosomething
}
});
}
}
Hope it is not correct to wrap the content of dialog as it might disrupt the view in tablets and larger devices.
Anyhow, basing upon your requirement.. hope this link works

Change this EditText
android.support.v7.widget.AppCompatEditText
to this
android.support.design.widget.TextInputEditText
Full Code :
<android.support.design.widget.TextInputLayout
android:id="#+id/email_field"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="16dp"
android:hint="#string/email_phone"
android:paddingTop="48dp">
<android.support.design.widget.TextInputEditText
android:id="#+id/et_email"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:inputType="textEmailAddress"
android:paddingEnd="0dp"
android:paddingStart="8dp"
/>
</android.support.design.widget.TextInputLayout>
Try not using
<android.support.v7.widget.AppCompatEditText
instead use
<EditText
So you will get:
<EditText
android:id="#+id/et_email"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:inputType="textEmailAddress"
android:paddingEnd="0dp"
android:paddingStart="8dp" />
After doing a bit of research on the issue i found this post:
EditText added is not a TextInputEditText. Please switch to using that class instead
let me know if it helps you.
Ok, so I am getting a nullpointerexception in logcat when I am running my app, however I looked at other StackOverflow questions that were similar to mine and found that I had done everything right, so where is my error coming from?
here is my MainActivity:
public double inchSnow, durationStorm, peakSnow, peakTime, finalSnow, windSpeed, snowGround, result, avgSnow;
EditText inSnow, durnStorm, pSnow, pTime, fSnow, wSpeed, sGround;
protected void onCreate(Bundle savedInstanceState) {
final AlertDialog.Builder invalidNumber = new AlertDialog.Builder(actContext);
invalidNumber.setTitle("Blank Field!");
invalidNumber.setMessage("Seems like a field has been left blank, can you fix it?");
invalidNumber.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.cancel();
}
});
inSnow = (EditText) findViewById(R.id.inchesSnow);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getZip = (Button) findViewById(R.id.calculate);
final Intent intent = new Intent(this, com.boreas.snowdaycalculator.result.class);
getZip.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
try{
inchSnow = new Integer(inSnow.getText().toString()).intValue();
}catch (NumberFormatException ex){
final AlertDialog alertDialog = invalidNumber.create();
invalidNumber.show();
}
Intent myIntent = new Intent(MainActivity.this, result.class);
myIntent.putExtra("inchSnow",inchSnow);
startActivity(myIntent);
}
});
}

Anyone have any ideas on what I am doing wrong? Thanks.
You need to place
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
before all other calls in method. findViewById() will return null until you set the content view. And more importantly, super.onCreate(savedInstanceState) will create the activity to work with.
Put the line:
inSnow = (EditText) findViewById(R.id.inchesSnow);
after the line:
setContentView(R.layout.activity_main);
Here's my xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

and here's my java:
public class LogInActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.loginactivity);
final RadioButton radio_on = (RadioButton) findViewById(R.id.on);
final RadioButton radio_off = (RadioButton) findViewById(R.id.off);
Button launch = (Button)findViewById(R.id.login_button);
launch.setOnClickListener(new OnClickListener()
{
public void onClick(View v) {
EditText usernameEditText = (EditText) findViewById(R.id.txt_username);
EditText passwordEditText = (EditText) findViewById(R.id.txt_password);
TextView loginTextView = (TextView)findViewById(R.id.tv_error);
String sUserName = usernameEditText.getText().toString();
String sPassword = passwordEditText.getText().toString();
if(sUserName.equals("numlock") && sPassword.equals("numlock")) {
Intent intent = new Intent(LogInActivity.this, HomeActivity.class);
startActivity(intent);
}
else {
loginTextView.setText("Login failed. Username and/or password doesn't match.");
}
}
});
}
}
I want to assign the keep me logged in state on the radio buttons. Any help?
you should save the login credentials in sharedPreferences or Sqlite and on login activity check if you find any saved data then login with the saved data else ask user for credentials..
You can do it by using SharedPreference, Static variables or by Application class which will helps you in keeping the state of the User
