转自：http://www.cnblogs.com/salam/archive/2011/06/28/1873654.html

 

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();
