Android带文字的ImageButton实现

实际上，ImageButton是不能添加文字的，所以我选择将ImageView控件和TextView控件封装在一个LinearLayout里面，整个LinearLayout就是一个按钮，然后对它监听单击等动作。

首先贴上layout.xml里面的布局设计：

<LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:id="@+id/bt"> 
        <ImageView
            android:id="@+id/ib"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ringlove"
            android:background="#00000000"
        /> 
        <TextView
            android:id="@+id/tv"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/cs"
            android:paddingLeft="20px"
        /> 
</LinearLayout>

然后是java代码实现：（注意，m_ll.setClickable(true);这句一定不能少）

package com.droidX.wcs233; 
  
import android.app.Activity; 
import android.graphics.Color; 
import android.os.Bundle; 
import android.view.MotionEvent; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.view.View.OnTouchListener; 
import android.widget.LinearLayout; 
import android.widget.Toast; 
  
public class testActivity extends Activity { 
    LinearLayout m_ll; 
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.main); 
        m_ll=(LinearLayout)findViewById(R.id.bt); 
        m_ll.setClickable(true); 
        m_ll.setOnClickListener(ocl); 
        m_ll.setOnTouchListener(otl); 
    } 
      
    public OnClickListener ocl=new OnClickListener() { 
          
        @Override
        public void onClick(View v) { 
            // TODO Auto-generated method stub 
            Toast.makeText(getApplicationContext(), "yes", Toast.LENGTH_SHORT).show(); 
        } 
    }; 
      
    public OnTouchListener otl=new OnTouchListener() { 
          
        @Override
        public boolean onTouch(View v, MotionEvent event) { 
            // TODO Auto-generated method stub 
            if(event.getAction()==MotionEvent.ACTION_DOWN) 
            { 
                m_ll.setBackgroundColor(Color.rgb(127,127,127)); 
            } 
            else if(event.getAction()==MotionEvent.ACTION_UP) 
            { 
                m_ll.setBackgroundColor(Color.TRANSPARENT); 
            } 
            return false; 
        } 
    }; 
}
