    setContentView(R.layout.main);

    findViewById(R.id.btnSimpleToast).setOnClickListener(this);

    findViewById(R.id.btnCustomToast).setOnClickListener(this);
    findViewById(R.id.btnRunToastFromOtherThread).setOnClickListener(this);

  }

  public void showToast() {
    handler.post(new Runnable() {

      @Override
      public void run() {
        Toast.makeText(getApplicationContext(), "我来自其他线程！",
            Toast.LENGTH_SHORT).show();

      }
    });
  }

  @Override
  public void onClick(View v) {
    Toast toast = null;
    switch (v.getId()) {
    case R.id.btnSimpleToast:
      Toast.makeText(getApplicationContext(), "默认Toast样式",
          Toast.LENGTH_SHORT).show();
      break;
    case R.id.btnSimpleToastWithCustomPosition:
      toast = Toast.makeText(getApplicationContext(), "自定义位置Toast",
          Toast.LENGTH_LONG);
      toast.setGravity(Gravity.CENTER, 0, 0);
      toast.show();
      break;
    case R.id.btnSimpleToastWithImage:
      toast = Toast.makeText(getApplicationContext(), "带图片的Toast",
          Toast.LENGTH_LONG);
      toast.setGravity(Gravity.CENTER, 0, 0);
      LinearLayout toastView = (LinearLayout) toast.getView();
      ImageView imageCodeProject = new ImageView(getApplicationContext());
      imageCodeProject.setImageResource(R.drawable.ic_launcher);
      toastView.addView(imageCodeProject, 0);
      toast.show();
      break;
    case R.id.btnCustomToast:
      LayoutInflater inflater = getLayoutInflater();
      View layout = inflater.inflate(R.layout.custom,
          (ViewGroup) findViewById(R.id.llToast));
      ImageView image = (ImageView) layout
          .findViewById(R.id.tvImageToast);
      image.setImageResource(R.drawable.ic_launcher);
      TextView title = (TextView) layout.findViewById(R.id.tvTitleToast);
      title.setText("Attention");
      TextView text = (TextView) layout.findViewById(R.id.tvTextToast);
      text.setText("完全自定义Toast");
      toast = new Toast(getApplicationContext());
      toast.setGravity(Gravity.RIGHT | Gravity.TOP, 12, 40);
      toast.setDuration(Toast.LENGTH_LONG);
      toast.setView(layout);
      toast.show();
      break;
    case R.id.btnRunToastFromOtherThread:
      new Thread(new Runnable() {
        public void run() {
          showToast();
        }
