Android应用无法使用。 [英] Android app is not working .

问题描述

我正在创建一个应用程序，启动一个覆盖按钮，当切换开关打开时，该覆盖按钮保持在所有其他活动之上。



我有以下三个班级在eclipse中没有显示错误。



MainActivity类 -

I am making an app which starts an overlay button which stays on top of all other activities when the toggle switch is on .

I have the following three classes with no errors shown in eclipse .

MainActivity class-

public class MainActivity extends ActionBarActivity {
  @Override
    protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);

      if (savedInstanceState == null) {
	getSupportFragmentManager().beginTransaction().add(R.id.container, new PlaceholderFragment()).commit();
      }
    }
	
    public void openOverlayButton(View view) {
      // Is the toggle on?
      boolean on = ((Switch) view).isChecked();
	    
      if (on) {
        Intent intent = new Intent(this, TaskBarViewNew.class);
	startActivity(intent);
      } else {
	// Disable overlay button
      }

TaskBarViewNew class-

TaskBarViewNew class-

public class TaskBarViewNew extends Activity {
  @Override
    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      Intent svc = new Intent(this , OverlayButtonActivity.class);
      startService(svc);
      finish();
   }

OverlayBittonActivity只是一项单独工作的服务，但在这里它不起作用。我认为我在使用Intent时犯了一个错误。任何人都可以帮忙??

And the OverlayBittonActivity is just a service which works fine alone but here it is not working . I think I am doing a mistake in using Intent . Can anyone help??
