我无法找到一种方法来全屏显示相机.在代码示例中,他们使用比率优化来适应所有屏幕,但它只占屏幕高度的3/4左右.

这是我的AutoFitTextureView代码：

public class AutoFitTextureView extends TextureView {

private int mRatioWidth = 0;
private int mRatioHeight = 0;

public AutoFitTextureView(Context context) {
    this(context,null);
}

public AutoFitTextureView(Context context,AttributeSet attrs) {
    this(context,attrs,0);
}

public AutoFitTextureView(Context context,AttributeSet attrs,int defStyle) {
    super(context,defStyle);
}

/**
 * Sets the aspect ratio for this view. The size of the view will be measured based on the ratio
 * calculated from the parameters. Note that the actual sizes of parameters don't matter,that
 * is,calling setAspectRatio(2,3) and setAspectRatio(4,6) make the same result.
 *
 * @param width  Relative horizontal size
 * @param height Relative vertical size
 */
public void setAspectRatio(int width,int height) {
    if (width < 0 || height < 0) {
        throw new IllegalArgumentException("Size cannot be negative.");
    }
    mRatioWidth = width;
    mRatioHeight = height;
    requestLayout();
}

@Override
protected void onMeasure(int widthMeasureSpec,int heightMeasureSpec) {
    super.onMeasure(widthMeasureSpec,heightMeasureSpec);
    int width = MeasureSpec.getSize(widthMeasureSpec);
    int height = MeasureSpec.getSize(heightMeasureSpec);

    if (0 == mRatioWidth || 0 == mRatioHeight) {
        setMeasuredDimension(width,height);
    } else {
        if (width < height * mRatioWidth / mRatioHeight) {
            setMeasuredDimension(width,width * mRatioHeight / mRatioWidth);
        } else {
            setMeasuredDimension(height * mRatioWidth / mRatioHeight,height);
        }
    }
}

}

非常感谢您的帮助.
