Android特效 五种Toast具体解释

  Toast是Android中用来显示显示信息的一种机制，和Dialog不一样的是，Toast是没有焦点的，并且Toast显示的时间有限，过一定的时间就会自己主动消失。

1.默认效果:

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

2.自己定义显示位置效果:

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

 3.带图片效果:

代码
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.全然自己定义效果:

代码
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("全然自己定义Toast");
   toast = new Toast(getApplicationContext());
   toast.setGravity(Gravity.RIGHT | Gravity.TOP, 12, 40);
   toast.setDuration(Toast.LENGTH_LONG);
   toast.setView(layout);
   toast.show();

5.其它线程:

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