要使用TextureView,您需要遵循以下步骤:
<TextureView
android:id="@+id/textureView"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
private TextureView mTextureView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTextureView = findViewById(R.id.textureView);
}
mTextureView.setSurfaceTextureListener(new TextureView.SurfaceTextureListener() {
@Override
public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height) {
// 当SurfaceTexture可用时调用,可以在此处进行渲染或其他操作
}
@Override
public void onSurfaceTextureSizeChanged(SurfaceTexture surfaceTexture, int width, int height) {
// 当SurfaceTexture尺寸更改时调用,可以在此处重新设置渲染器或其他操作
}
@Override
public boolean onSurfaceTextureDestroyed(SurfaceTexture surfaceTexture) {
// 当SurfaceTexture销毁时调用,可以在此处释放资源或停止渲染
return false;
}
@Override
public void onSurfaceTextureUpdated(SurfaceTexture surfaceTexture) {
// 当SurfaceTexture更新时调用,可以在此处执行其他操作
}
});
@Override
public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height) {
Surface surface = new Surface(surfaceTexture);
// 创建渲染器
// Renderer renderer = new Renderer(surface);
// renderer.startRendering();
// 执行其他渲染操作
// ...
}
请注意,TextureView只是一个视图,需要自己实现渲染逻辑,例如使用SurfaceTexture创建渲染器进行视频播放或图形渲染等。
