android开发(二十) Toast五种特效详解

   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，而且Toast显示的时间有限，过一定的时间就会自动消失。

一  默认效果:

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

二  自定义显示位置效果:

代码:

   toast = Toast.makeText(getApplicationContext(),"自定义位置Toast", Toast.LENGTH_LONG);

   toast.setGravity(Gravity.CENTER, 0, 0);

   toast.show();

三  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();

四  完全自定义效果:

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("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();

五  其他线程:

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