安卓通知消息Toast

安卓Toast消息就是在屏幕下方出现短暂的提示消息。

下面展示了5种效果：

1. 默认效果
   

   (adsbygoogle = window.adsbygoogle || []).push({});

   Toast.makeText(getApplicationContext(), "默认Toast样式",Toast.LENGTH_SHORT).show();

2. 自定义显示位置效果
   

   toast = Toast.makeText(getApplicationContext(),
    "自定义位置Toast", Toast.LENGTH_LONG);
   toast.setGravity(Gravity.CENTER, 0, 0);
   toast.show();

3. 带图片效果
   

   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.icon)；
   toastView.addView(imageCodeProject, 0);
   toast.show();

4. 完全自定义效果
   

      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.icon);
      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();

5. 其他线程

       public void run() {
       showToast();
       }   }).start();
