标签: android eclipse button onclicklistener logcat

当emulador完成加载时,我的应用程序死了。 Logcat这样说:

  1. I / Process(599):发送信号。 PID:599 SIG:9
  2. I / ActivityManager(91):进程com.example.nuevo(pid 599)具有 死亡。
  3. 然后当我选择应用程序时,Logcat说:

    1. W / ActivityManager(91):活动销毁超时 ActivityRecord {41503720 com.example.nuevo / .MainActivity}
    2. I /处理(617):发送信号。 PID:617 SIG:9
    3. W / InputManagerService(91):窗口已经聚焦,忽略了焦点增益: com.android.internal.view.IInputMethodClient$Stub$Proxy@4167df68
    4. I / ActivityManager(91):进程com.example.nuevo(pid 617)已经死亡。
    5. 我的代码:

      MainActivity.java:

      import android.app.Activity;
      import android.app.Fragment;
      import android.os.Bundle;

      import android.widget.TextView;
      
      
      
      public class MainActivity extends Activity implements OnClickListener {
      
          @Override
          protected void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);
              setContentView(R.layout.activity_main);
              View boton1 = findViewById(R.id.button1);
              boton1.setOnClickListener(this);
      
              if (savedInstanceState == null) {
                  getFragmentManager().beginTransaction()
                          .add(R.id.container, new PlaceholderFragment())
                          .commit();
              }
          }
      
      
          @Override
          public boolean onCreateOptionsMenu(Menu menu) {
      
              // Inflate the menu; this adds items to the action bar if it is present.
              getMenuInflater().inflate(R.menu.main, menu);
              return true;
          }
      
          @Override
          public boolean onOptionsItemSelected(MenuItem item) {
              // Handle action bar item clicks here. The action bar will
              // automatically handle clicks on the Home/Up button, so long
              // as you specify a parent activity in AndroidManifest.xml.
              int id = item.getItemId();
              if (id == R.id.action_settings) {
                  return true;
              }
              return super.onOptionsItemSelected(item);
          }
      
          /**

           */
          public static class PlaceholderFragment extends Fragment {

                  return rootView;

          }
      
      
          @Override

                  texto.setText("EL BOTON FUE SELECCIONADO");
              }
          }
      
      }
