public class MainActivity extends Activity implements TextureView.SurfaceTextureListener {

    private TextureView myTexture;

    @Override    protected void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        myTexture = new TextureView(this);
        myTexture.setSurfaceTextureListener(this);
        setContentView(myTexture);
        //setContentView(R.layout.activity_main);
    }
}
..................................................................................................................................................................
After that tharSurfaceTextureListener implement  override method.

...................................................................................................................................................................


@Overridepublic void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height) {

}

@Overridepublic void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {

}

@Overridepublic boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {
    return false;
}

@Overridepublic void onSurfaceTextureUpdated(SurfaceTexture surface) {

}
