setBackgroundColor

method

in

android.view.SurfaceView

@Override
public void setBackgroundColor(int color) {
  super.setBackgroundColor(color);
}

@Override
protected void onCreate(@Nullable final Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_surface_view);
  final SurfaceView surfaceView = (SurfaceView) findViewById(R.id.surface_view);
  surfaceView.setBackgroundColor(Color.RED);
}

public GameView(Context context) {
  super(context);
  addView(
      LayoutInflater.from(getContext()).inflate(R.layout.game_view, null),
      new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
  this.gameManager = new GameManager(getContext());
  this.surfaceView = (SurfaceView) findViewById(R.id.surface_view);
  this.scoreView = (TextView) findViewById(R.id.txt_score);
  this.highScoreView = (TextView) findViewById(R.id.txt_high_score);
  this.whiteView = findViewById(R.id.view_white);
  this.downArrowView = (ImageView) findViewById(R.id.img_arrow_down);
  this.arrowFadeOutAnim = AnimationUtils.loadAnimation(context, R.anim.arrow_fade_out);
  SurfaceHolder surfaceHolder = surfaceView.getHolder();
  surfaceHolder.addCallback(this);
  surfaceHolder.setFormat(PixelFormat.TRANSPARENT);
  surfaceView.setBackgroundColor(Color.TRANSPARENT);
  surfaceView.setZOrderOnTop(true);
}

surfaceHolder.setKeepScreenOn(true);
surfaceView.setFocusable(true);
surfaceView.setBackgroundColor(TRIM_MEMORY_BACKGROUND);
surfaceView.getHolder().addCallback(new SurfaceCallback());//为SurfaceView的句柄添加一个回调函数
