android自定义按钮

1》定义按钮布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android

rientation="horizontal"
      android:layout_gravity="center"
      android:layout_width="wrap_content"
      android:layout_height="fill_parent"
      >
<ImageView
         android:id="@+id/iconMoney"
         android:layout_width="25dp"
         android:layout_height="fill_parent"
         >
</ImageView>
<TextView
         android:id="@+id/numMeoney"
         android:layout_width="wrap_content"
         android:layout_height="fill_parent"
         android:gravity="center"
         android:text="4444"
         android:textSize="20dp"
         android:layout_marginTop="0dp"
         android:layout_marginBottom="3dp"
         android:layout_marginLeft="8dp"
         >
</TextView>
<ImageView
         android:layout_marginLeft="5dp"
         android:id="@+id/iconAdd"
         android:layout_width="25dp"
         android:layout_height="fill_parent"
         >
</ImageView>
</LinearLayout>

2》继承布局文件

package com.widget;

import android.content.Context;
import android.graphics.Bitmap;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;
import com.dreamplanegames.R;

public class MoneyView extends LinearLayout {

private ImageView iconMoney;
private TextView textView;

private ImageView Addmoney;

public MoneyView(Context context,AttributeSet attributeSet) {
      super(context, attributeSet);
      LayoutInflater.from(context).inflate(R.layout.money, this,true);//指定布局

      this.iconMoney = (ImageView)findViewById(R.id.iconMoney);
      this.textView = (TextView)findViewById(R.id.numMeoney);
      this.Addmoney=(ImageView)findViewById(R.id.iconAdd);

      this.setClickable(true);//可以点击
      this.setFocusable(true);
}

//设置控件内容
public void setText(String text) {
      this.textView.setText(text);
}

public void setTextColor(int color) {
      this.textView.setTextColor(color);
}

public void setTextSize(float size) {
      this.textView.setTextSize(size);
}

public void setImg(Bitmap img1,Bitmap img2) {
      this.iconMoney.setImageBitmap(img1);
      this.Addmoney.setImageBitmap(img2);
      //this.yes.setImageBitmap(img2);
}

}

3》控件的调用

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android

rientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<ImageView android:id="@+id/mainMenuImage"
      android:src="@drawable/xk_bg2"
      android:scaleType="fitXY"
      android:layout_width="match_parent"
      android:layout_height="match_parent">
</ImageView>
//调用自定义控件
<com.widget.MoneyView--------------------类名
         android:layout_width="wrap_content"
         android:layout_height="30dp"
         android:id="@+id/btnMoney"
         android:layout_alignParentLeft="true"
         android:layout_alignParentTop="true"
         android:layout_marginTop="20dp"
         android:layout_marginLeft="20dp"
         >
</com.widget.MoneyView>

</RelativeLayout>

4》到相应的activity调用
public class SFMainMenu extends Activity implements View.OnClickListener
{
public MoneyView moneyview;
@Override
public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      //设置全屏
      getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
      //去除应用程序标题
      this.requestWindowFeature(Window.FEATURE_NO_TITLE);
      //设置竖屏
      setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
      setContentView(R.layout.main);

//获取自定义按钮
moneyview=(MoneyView)findViewById(R.id.btnMoney);

//调用自定义控件的函数设置控件内容
      moneyview.setImg(BitmapFactory.decodeResource(getResources(), R.drawable.money),BitmapFactory.decodeResource(getResources(), R.drawable.add));
      moneyview.setText(""+myPointBalance);

      //自定义按钮响应事件
      moneyview.setOnClickListener(new OnClickListener() {

         @Override
         public void onClick(View v) {
            // TODO Auto-generated method stub

         }
      });

}
//返回键
@Override
public void onBackPressed() {
      super.onBackPressed();

}

}
