android中的（singleLine）单行显示 none start middle

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

         }});

     }

}
