出于某种原因,当我尝试设置textview的文本时,我的应用程序崩溃了？我怎么能过来这个呢.

private TextView strStatus;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
    txtUsername = (EditText) findViewById(R.id.username);
    strStatus = (TextView) findViewById(R.id.status);
    //strStatus.setText("test"); // SEEMS TO BE CAUSING THE CRASH
    setContentView(R.layout.main);   
}

<TextView
android:id="@+id/status"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
