我在activity_main中有一个图像视图，在content_main中有其他图像视图，我想合并图像视图并截取它的截图，但它没有显示content_main的图像。以下是它的图片。

我想用里面的照片拍摄的图像

以下是我完成图像捕捉的代码。

View vScreenShot = findViewById(R.id.frame_memecontent);

FrameLayout z = (FrameLayout) findViewById(R.id.frame_memecontent);
if(z!=null) {
     int totalHeight = z.getChildAt(0).getHeight();
     int totalWidth = z.getChildAt(0).getWidth();
     vScreenShot.layout(0, 0, totalWidth, totalHeight);
}
vScreenShot.buildDrawingCache(true);

//create bitmap and save drawing cache
Bitmap bitmapSetDrawingChache = Bitmap.createBitmap(vScreenShot.getDrawingCache());

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

bitmapSetDrawingChache.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOutputStream);

// saving in sdcard
File file = new File(Environment.getExternalStorageDirectory().toString() + File.separator + "Birthday Invitation Maker" + File.separator);
if(!file.exists())
    file.mkdirs();

String imageName = "Image-" + DateFormat.getDateTimeInstance().format(new Date()) + ".jpg";

File f = new File(file,imageName);
try {

    FileOutputStream fileOutputStream = new FileOutputStream(f);
    fileOutputStream.write(byteArrayOutputStream.toByteArray());
    fileOutputStream.close();
    Toast.makeText(TemplateOne.this, "Image Saved",Toast.LENGTH_SHORT).show();
} catch (IOException e) {
    e.printStackTrace();
}

欢迎任何建议/意见。提前谢谢。

您正在创建仅一个布局的图像，即vScreenShot

Bitmap bitmapSetDrawingChache = Bitmap.createBitmap(vScreenShot.getDrawingCache());

vScreenShot仅包含没有图片的框架。

解决方案是在vScreenShot内包含您的图片布局，或者拍摄父版面

的屏幕截图

<RelativeLayout android:id="@+id/my_layout">

     // include layout which contains your template/frame
     // include layout which contains your rounded ImageView.

</RelativeLayout>

现在您可以截取my_layout

的屏幕截图了

RelativeLayout my_layout=(RelativeLayout)findViewById(R.id.my_layout);
Bitmap bitmapSetDrawingChache = Bitmap.createBitmap(my_layout.getDrawingCache());

合并两个图像并获取布局android的截图
