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。

1.默认效果:

代码:

[li]Toast.makeText(getApplicationContext(), "默认Toast样式",[/li][li]     Toast.LENGTH_SHORT).show();
[/li]

复制代码
2.自定义显示位置效果:

代码:

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

3.带图片效果:
代码

[li]toast = Toast.makeText(getApplicationContext(),[/li][li]     "带图片的Toast", Toast.LENGTH_LONG);[/li][li]   toast.setGravity(Gravity.CENTER, 0, 0);[/li][li]   LinearLayout toastView = (LinearLayout) toast.getView();[/li][li]   ImageView imageCodeProject = new ImageView(getApplicationContext());[/li][li]   imageCodeProject.setImageResource(R.drawable.icon);[/li][li]   toastView.addView(imageCodeProject, 0);[/li][li]   toast.show();
[/li]

复制代码

4.完全自定义效果:

代码

[li]LayoutInflater inflater = getLayoutInflater();[/li][li]   View layout = inflater.inflate(R.layout.custom,[/li][li]     (ViewGroup) findViewById(R.id.llToast));[/li][li]   ImageView image = (ImageView) layout[/li][li]     .findViewById(R.id.tvImageToast);[/li][li]   image.setImageResource(R.drawable.icon);[/li][li]   TextView title = (TextView) layout.findViewById(R.id.tvTitleToast);[/li][li]   title.setText("Attention");[/li][li]   TextView text = (TextView) layout.findViewById(R.id.tvTextToast);[/li][li]   text.setText("完全自定义Toast");[/li][li]   toast = new Toast(getApplicationContext());[/li][li]   toast.setGravity(Gravity.RIGHT | Gravity.TOP, 12, 40);[/li][li]   toast.setDuration(Toast.LENGTH_LONG);[/li][li]   toast.setView(layout);[/li][li]   toast.show();
[/li]

5.其他线程:
代码:

[li]new Thread(new Runnable() {[/li][li]    public void run() {[/li][li]     showToast();[/li][li]    }[/li][li]   }).start();
[/li]
