自定义控件

请看例子:

定义一个/res/layout/control.xml

<?xml version="1.0" encoding="utf-8"?>  
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
    android:orientation="horizontal"  
    android:layout_width="fill_parent"  
    android:layout_height="fill_parent"  
    >  
<ImageView  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:id="@+id/iv"  
    android:src="@drawable/icon"  
    android:paddingTop="5dip"  
    android:paddingBottom="5dip"  
    android:paddingLeft="5dip"  
    android:layout_gravity="center_vertical"  
    />
<TextView  
    android:layout_height="wrap_content"  
    android:text="确定"  
    android:textColor="#000000"  
    android:id="@+id/tv"  
    android:layout_marginLeft="8dip" android:layout_marginRight="10dip" 
    android:layout_gravity="center_vertical" android:layout_width="wrap_content"/>  
</LinearLayout>

自定义控件的类ImageBt.java

package com.notice.ib;  
  
import com.control.R;

import android.content.Context;  
import android.util.AttributeSet;  
import android.view.LayoutInflater;  
import android.widget.ImageView;  
import android.widget.LinearLayout;  
import android.widget.TextView;  
  
public class ImageBt extends LinearLayout {  
  
    private ImageView iv;  
    private TextView  tv;  
  
    public ImageBt(Context context) {  
        this(context, null);  
    }  
  
    public ImageBt(Context context, AttributeSet attrs) {  
        super(context, attrs);  
        // 导入布局  
        LayoutInflater.from(context).inflate(R.layout.control, this, true);  
        iv = (ImageView) findViewById(R.id.iv);  
        tv = (TextView) findViewById(R.id.tv);  
    }  
  
    /** 
     * 设置图片资源 
     */  
    public void setImageResource(int resId) {  
        iv.setImageResource(resId);  
    }  
  
    /** 
     * 设置显示的文字 
     */  
    public void setTextViewText(String text) {  
        tv.setText(text);  
    }  
  
} 

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
	<RelativeLayout  
         android:orientation="horizontal"  
         android:layout_width="fill_parent"  
         android:layout_height="wrap_content"  
         android:layout_gravity="center_vertical"  
         >  
         <com.notice.ib.ImageBt  
             android:id="@+id/bt_confirm"  
             android:layout_height="wrap_content"  
             android:layout_width="wrap_content"  
             android:layout_alignParentBottom="true"  
             android:background="#FFFFFF"
             android:clickable="true"  
             android:focusable="true"  
             />  
         <com.notice.ib.ImageBt  
             android:id="@+id/bt_cancel"  
             android:layout_toRightOf="@id/bt_confirm"  
             android:layout_height="wrap_content"  
             android:layout_width="wrap_content"  
             android:layout_alignParentBottom="true"  
             android:background="#FFFFFF"  
             android:clickable="true"  
             android:focusable="true"  
             android:layout_marginLeft="10px"
            />  
	</RelativeLayout>
</LinearLayout>

主Activity类

package com.control;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;

import com.notice.ib.ImageBt;

public class ControlActivity extends Activity {
	private ImageBt ib1;  
    private ImageBt ib2;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        ib1 = (ImageBt) findViewById(R.id.bt_confirm);  
        ib2 = (ImageBt) findViewById(R.id.bt_cancel);  
  
        ib1.setTextViewText("确定");  
        ib1.setImageResource(R.drawable.icon);  
        ib2.setTextViewText("取消");  
        ib2.setImageResource(R.drawable.icon);  
  
        ib1.setOnClickListener(new OnClickListener() {  
  
            @Override  
            public void onClick(View v) {  
                    //在这里可以实现点击事件  
            }  
        });
    }
}
