要使用TextureView,您需要遵循以下步驟:
<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) {
// 當SurfaceTexture可用時調用,可以在此處進行渲染或其他操作
}
@Override
public void onSurfaceTextureSizeChanged(SurfaceTexture surfaceTexture, int width, int height) {
// 當SurfaceTexture尺寸更改時調用,可以在此處重新設置渲染器或其他操作
}
@Override
public boolean onSurfaceTextureDestroyed(SurfaceTexture surfaceTexture) {
// 當SurfaceTexture銷毀時調用,可以在此處釋放資源或停止渲染
return false;
}
@Override
public void onSurfaceTextureUpdated(SurfaceTexture surfaceTexture) {
// 當SurfaceTexture更新時調用,可以在此處執行其他操作
}
});
@Override
public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height) {
Surface surface = new Surface(surfaceTexture);
// 創建渲染器
// Renderer renderer = new Renderer(surface);
// renderer.startRendering();
// 執行其他渲染操作
// ...
}
請注意,TextureView只是一個視圖,需要自己實現渲染邏輯,例如使用SurfaceTexture創建渲染器進行視頻播放或圖形渲染等。
