android中的（singleLine）单行显示 none start middle

http://www.cnblogs.com/firecode/archive/2012/04/23/2466711.html

第一个button 什么都没写。   后面省略号

android:ellipsize="none"   none就没有省略号了

android:ellipsize="start"  省略好放到起始的位置

android:ellipsize="middle" 省略号放到中间的位置

android:ellipsize="end"     省略号房子尾部的位置

android:ellipsize="marquee"   跑马灯效果，从左往右的跑马灯效果

INVISIBLE 不显眼的 用法

TestActivity.java

public class TestActivity extends Activity {
    Button btn1;
    Button btn;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super .onCreate(savedInstanceState);
        setContentView(R.layout.main);
        btn1  = (Button) this .findViewById(R.id.btn1);

        btn = (Button) this .findViewById(R.id.btn);

        btn.setOnClickListener( new OnClickListener(){

        public void onClick(View v){
            btn1.setVisibility(View.INVISIBLE);　　　　 //换用GONE就会直接删除第一个按钮空间
        }});
    }
}
