Question

我截取了布局的屏幕截图，但给出的图像与显示运行时视图不同。我使用com.github.chrisbanes.photoview.PhotoView库进行缩放以放大图像上的手势。

<LinearLayout
            android:id="@+id/ContentLinearLayout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@drawable/random"
            android:orientation="horizontal"
            android:weightSum="2">

            <androidx.cardview.widget.CardView
                android:id="@+id/ImageViewLeftCard"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                app:cardCornerRadius="20dp"
                android:layout_margin="1dp"
                android:layout_weight="1">
            <com.github.chrisbanes.photoview.PhotoView
                android:id="@+id/ImageViewLeft"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="@color/blackcolor"/>
            </androidx.cardview.widget.CardView>

            <androidx.cardview.widget.CardView
                android:id="@+id/ImageViewRightCard"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                app:cardCornerRadius="20dp"
                android:layout_margin="1dp"
                android:layout_weight="1">
            <com.github.chrisbanes.photoview.PhotoView
                android:id="@+id/ImageViewRight"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="@color/blackcolor" />
            </androidx.cardview.widget.CardView>

</LinearLayout>

截图后我需要与显示视图相同的图像。

我正在使用此代码截屏。

private void screenshot(View v){
    v.setDrawingCacheEnabled(true);
    Bitmap bitmap = Bitmap.createBitmap(v.getDrawingCache());
    v.setDrawingCacheEnabled(false);
}

我所面临的问题..用简单的措辞，我需要截图后带有圆角的图像。

Answer 1

尝试

private Bitmap extractBitmap(ViewGroup iViewGroup) {

int width = iViewGroup.getWidth();
int height = iViewGroup.getWidth();

Bitmap createBitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);

Canvas canvas = new Canvas(createBitmap);

iViewGroup.draw(canvas);

return createBitmap;

  }
}

Answer 2

创建可绘制资源

round_shape.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <corners android:radius="20dp" />
</shape>

并将此可绘制对象设置为 com.github.chrisbanes.photoview.PhotoView

的背景

<LinearLayout
    android:id="@+id/ContentLinearLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/random"
    android:orientation="horizontal"
    android:weightSum="2">

    <androidx.cardview.widget.CardView
        android:id="@+id/ImageViewLeftCard"
        app:cardCornerRadius="20dp"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_margin="1dp"
        android:layout_weight="1">

        <com.github.chrisbanes.photoview.PhotoView
            android:id="@+id/ImageViewLeft"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@drawable/round_shape"
            android:background="@color/blackcolor" />
    </androidx.cardview.widget.CardView>

    <androidx.cardview.widget.CardView
        android:id="@+id/ImageViewRightCard"
        app:cardCornerRadius="20dp"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_margin="1dp"
        android:layout_weight="1">

        <com.github.chrisbanes.photoview.PhotoView
            android:id="@+id/ImageViewRight"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@drawable/round_shape"
            android:background="@color/blackcolor" />
    </androidx.cardview.widget.CardView>

</LinearLayout>

并使用与获取屏幕截图相同的功能。

屏幕截图与“显示”视图不同
