本文主要实现一个小的扒开美女衣服的游戏项目
效果如下：
项目布局设计：
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" > <ImageView
android:id="@+id/iv_after"
android:layout_width="wrap_content"
android:layout_height="wrap_content" /> <ImageView
android:id="@+id/iv_pre"
android:layout_width="wrap_content"
android:layout_height="wrap_content" /> </FrameLayout>
逻辑部分代码：
public class MainActivity extends Activity {
private ImageView iv_after;
private ImageView iv_before;
private Bitmap alterBitmap;
private Canvas canvas;
private Paint paint;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BitmapFactory.Options opts = new Options();
opts.inSampleSize = 2;
iv_after = (ImageView) findViewById(R.id.iv_after);
iv_before = (ImageView) findViewById(R.id.iv_pre);
Bitmap after = BitmapFactory.decodeResource(getResources(),
R.drawable.after19, opts);
Bitmap before = BitmapFactory.decodeResource(getResources(),
R.drawable.pre19, opts);
// 可以修改的空白的bitmap
alterBitmap = Bitmap.createBitmap(before.getWidth(),
before.getHeight(), before.getConfig());
canvas = new Canvas(alterBitmap);
paint = new Paint();
paint.setStrokeWidth(5);
paint.setColor(Color.BLACK);
canvas.drawBitmap(before, new Matrix(), paint);
iv_after.setImageBitmap(after);
iv_before.setImageBitmap(alterBitmap);
iv_before.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
break;
case MotionEvent.ACTION_MOVE:
int newX = (int) event.getX();
int newY = (int) event.getY();
for (int i = -6; i < 6; i++) {
for (int j = -6; j < 6; j++) {
alterBitmap.setPixel(i + newX, j + newY,
Color.TRANSPARENT);
}
}
iv_before.setImageBitmap(alterBitmap);
break;
case MotionEvent.ACTION_UP:
break;
default:
break;
}
return true;
}
});
}
}
