如何指定视频视图的位置？（左上、右上、左下……等）

我有一个 VideoView，我知道如何将其在屏幕上居中，但现在我需要动态地（java 代码，而不是 xml 代码）指定屏幕上的位置。

这是我的实际代码：

    VideoView vv = new VideoView(this);
    this.setContentView(vv);
    android.widget.FrameLayout.LayoutParams vvParams = (android.widget.FrameLayout.LayoutParams) vv.getLayoutParams();
    vvParams.gravity=17; //gravity 17 = center horizontal & vertical
    vvParams.width=150;
    vv.setLayoutParams(vvParams);        
    String fileName = "android.resource://" + getPackageName() + "/" + R.raw.v;
    vv.setVideoURI(Uri.parse(fileName));
    vv.start();

这些是我想要指定的可能位置：（

垂直/水平）

左上、中上、右上
中左、中中、右中
左下、中下、右下

如何指定这些位置动态地使用java代码吗？

i have a VideoView that i know how to center it on the screen, but now i need to specify dinamically (java code, not xml code) the position on the screen.

This is my actual code:

    VideoView vv = new VideoView(this);
    this.setContentView(vv);
    android.widget.FrameLayout.LayoutParams vvParams = (android.widget.FrameLayout.LayoutParams) vv.getLayoutParams();
    vvParams.gravity=17; //gravity 17 = center horizontal & vertical
    vvParams.width=150;
    vv.setLayoutParams(vvParams);        
    String fileName = "android.resource://" + getPackageName() + "/" + R.raw.v;
    vv.setVideoURI(Uri.parse(fileName));
    vv.start();

These are the possible positions i want to specify:

(vertical/horizontal)

top left, top center, top right
center left, center center, center right
bottom left, bottom center, bottom right

How to specify these possitions with java code dinamically?

让您的 VideoView 成为 RelativeLayout，然后像这样更新 LayoutParams：

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams();

// Horizontal alignment - choose as appropriate
lp.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
//lp.addRule(RelativeLayout.CENTER_HORIZONTAL);
//lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);

// Vertical alignment - choose as appropriate
lp.addRule(RelativeLayout.ALIGN_PARENT_TOP);
//lp.addRule(RelativeLayout.CENTER_VERTICAL);
//lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);

vv.setLayoutParams(lp);

Make your VideoView the child of a RelativeLayout, and then update the LayoutParams like this:

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams();

// Horizontal alignment - choose as appropriate
lp.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
//lp.addRule(RelativeLayout.CENTER_HORIZONTAL);
//lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);

// Vertical alignment - choose as appropriate
lp.addRule(RelativeLayout.ALIGN_PARENT_TOP);
//lp.addRule(RelativeLayout.CENTER_VERTICAL);
//lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);

vv.setLayoutParams(lp);
