  • Android里五种 Toast方式

    Toast用于向用户显示一些帮助/提示。下面我做了5中效果,来说明Toast的强大,定义一个属于你自己的Toast。1.默认效果

    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

    new Thread(new Runnable() {
     
       public void run() {
     
        showToast();
     
        }
     
       }).start();
