android自定義按鈕 1》定義按鈕布局文件 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" androidrientation="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》繼承布局文件 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);//可以點擊 this.setFocusable(true); }
//設置控件內容 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》控件的調用 <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" androidrientation="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> //調用自定義控件 <com.widget.MoneyView--------------------類名 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》到相應的activity調用 public class SFMainMenu extends Activity implements View.OnClickListener { public MoneyView moneyview; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //設置全屏 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); //去除應用程序標題 this.requestWindowFeature(Window.FEATURE_NO_TITLE); //設置豎屏 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); setContentView(R.layout.main); //獲取自定義按鈕 moneyview=(MoneyView)findViewById(R.id.btnMoney); //調用自定義控件的函數設置控件內容 moneyview.setImg(BitmapFactory.decodeResource(getResources(), R.drawable.money),BitmapFactory.decodeResource(getResources(), R.drawable.add)); moneyview.setText(""+myPointBalance);
//自定義按鈕響應事件 moneyview.setOnClickListener(new OnClickListener() {
@Override public void onClick(View v) { // TODO Auto-generated method stub } });
} //返回鍵 @Override public void onBackPressed() { super.onBackPressed();
}
}
