Android基于ImageView绘制的开关按钮效果示例

<ImageView  Android:id="@+id/start"  android:layout_width="150.px"  android:layout_height="80.px"  android:src="@drawable/start"  android:layout_x="120.0px"  android:layout_y="250.0px"/>

public class two extends Activity implements OnClickListener{private ImageView start =null; // 开始protected boolean isBrewing = false; // 按钮置换public void onCreate(Bundle savedInstanceState) {    //设置全屏    super.onCreate(savedInstanceState);    requestWindowFeature(Window.FEATURE_NO_TITLE);    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,      WindowManager.LayoutParams.FLAG_FULLSCREEN);    setContentView(R.layout.two);    // 绑定    start = (ImageView) findViewById(R.id.start);  start.setOnClickListener(this);}//开始public void startView(){Bitmap bmp=BitmapFactory.decodeResource(getResources(), R.drawable.stop);//打开资源图片    start.setImageBitmap(bmp);    isBrewing = true;}//停止public void stopView(){Bitmap bmp=BitmapFactory.decodeResource(getResources(), R.drawable.start);//打开资源图片    start.setImageBitmap(bmp);    isBrewing = false;}  @Override  public void onClick(View v) {    if(v==start){      if(isBrewing)        stopView();      else        startView();    }  }}
