Clear text in EditText when entered [duplicate]

Question

I'm trying to set and onclicklistener so that when I click within the edittext element it will clear its current contents. Is there something wrong here? When I compile this code I get a force quit and ActivityManager: Can't dispatch DDM chunk 4d505251: no handler defined error.

public class Project extends Activity implements OnClickListener {
    /** Called when the activity is first created. */
    EditText editText = (EditText)findViewById(R.id.editText1);
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        editText.setOnClickListener(this);

        setContentView(R.layout.main);

    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        editText.setText("");
    }
}

Answer 1

Also you can use code below

editText.getText().clear();

Answer 2

First you need to call setContentView(R.layout.main) then all other initialization.

Please try below Code.

public class Trackfolio extends Activity implements OnClickListener {
    /** Called when the activity is first created. */
    public EditText editText;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        editText = (EditText) findViewById(R.id.editText1);
        editText.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        editText.getText().clear(); //or you can use editText.setText("");
    }
}

Answer 3

just use the android:hint attribute in your EditText. This text shows up when the box is empty and not focused, but disappears upon selecting the EditText box.
