This is my first post on this platform, if I have done wrong, please forgive me. These codes can run in eclipse without error, when the app run on the phone and clicked the button, the app exited with “Unfortunately，*** has stopped”. Firstly, I thought my phone is not compatible with the program, so I used the emulator and got the same result.
This is the code:
public class MainActivity extends Activity implements OnClickListener{
private Button button;
private EditText editText;
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.text_layout);
button = (Button) findViewById(R.id.test_button);
editText =(EditText) findViewById(R.id.edit_text);
button.setOnClickListener(this);
}
@Override
public void onClick(View v){
switch (v.getId()){
case R.id.test_button:
String inputText = editText.getText().toString();
Toast.makeText(MainActivity.this, inputText, Toast.LENGTH_SHORT).show();
break;
default:
break;
}
}
}
String inputText = editText.getText().toString()
replaced by String inputText = hello , that would be run on the phone successfully with "hello" when clicked hte button.
Thank you for helping me solve this problem
<Button
android:id="@+id/test_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Button"/>
<EditText
android:name="@+id/edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Type something here"
android:maxLines="2"
/>
