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();
