如何加载 TextureView 作为视图的一部分

Question

我想加载 TextureView 作为布局的一部分。我在一些示例之前看到它在 setContentView 函数中使用 TextureView。

    ...
    TextureView textureView = new TextureView(this);
    textureView.setSurfaceTextureListener(this);

    setContentView(textureView);

但我想加载此 textureView 作为 xml 布局的一部分。我该怎么办？

试试这个，你可以像这样在你的布局中直接添加 TextureView

<LinearLayout
    android:id="@+id/rootView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/colorPrimaryDark"
    android:orientation="vertical">

    <TextureView
        android:id="@+id/textureView1"
        android:layout_width="350dp"
        android:layout_height="350dp"
        android:layout_below="@+id/textView1" />
</LinearLayout>

或者您可以像这样在布局中动态添加 TextureView

public class MainActivity extends AppCompatActivity implements TextureView.SurfaceTextureListener {

    LinearLayout rootLinearLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        rootLinearLayout = findViewById(R.id.rootView);
        TextureView textureView = new TextureView(this);
        textureView.setSurfaceTextureListener(this);
        rootLinearLayout.addView(textureView);


    }

    @Override
    public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int i, int i1) {

    }

    @Override
    public void onSurfaceTextureSizeChanged(SurfaceTexture surfaceTexture, int i, int i1) {

    }

    @Override
    public boolean onSurfaceTextureDestroyed(SurfaceTexture surfaceTexture) {
        return false;
    }

    @Override
    public void onSurfaceTextureUpdated(SurfaceTexture surfaceTexture) {

    }
}

你可以直接用TextureView在布局中使用它，用findViewById()获取它。

  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <TextureView
        android:id="@+id/texture_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>
