3,388 PointsHelp please - Entering StartButton related java code breaks my app.
adding StartButton related code generates error while running on emulator. Error Message displayed is "Unfortunately, Interactive Story has stopped".
I tried following,
1 declaring mStartButton as private shows that - Private field 'mStartButton' is never assigned. so I declared it public and message goes away.
Here is my MainActivity.java code:
package au.com.relteksys.interactivestory;
import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.Toast;
public class MainActivity extends Activity {
private EditText mNameField; private Button mStartButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mNameField = (EditText)findViewById(R.id.nameEditText);
mStartButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String name = mNameField.getText().toString();
Toast.makeText(MainActivity.this, name, Toast.LENGTH_LONG).show();
}
});
}
}

19,746 PointsBefore the setOnClickListener for mStartButton you need to set the mStartButton.
Below where you set mNameField you can also set the Button so your code should have:
mNameField = (EditText)findViewById(R.id.nameEditText);
mStartButton = (Button) findViewById(R.id.startButton);
Hope that helps.
