如何使用 Intent.ACTION_SEND 共享 xml 布局

Question

我到处搜索，但找不到解决方案...

我有两个 xml 布局供分享。我已经膨胀并正确分配给视图。

shareLayout = LayoutInflater.from(getApplicationContext()).inflate(R.layout.share_every_for_self_game_layout, null);
    contentView = (LinearLayout) shareLayout.findViewById(R.id.share_container_layout_id);

问题是分享的图片总是空的。

这是我的代码

private void shareResultToFacebook(){
    try {
        Bitmap bitmap = getBitmapFromView(contentView);

        Intent shareIntent = new Intent();
        shareIntent.setAction(Intent.ACTION_SEND);
        shareIntent.putExtra(Intent.EXTRA_STREAM, getImageUri(this, bitmap));
        shareIntent.setType("image/jpeg");
        startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.send_to)));

    }catch (Exception e){
        e.getMessage();
    }

}

//create bitmap from view and returns it
private Bitmap getBitmapFromView(View view) {
    try {

        view.setDrawingCacheEnabled(true);

        view.buildDrawingCache();
        //Define a bitmap with the same size as the view
        Bitmap returnedBitmap = Bitmap.createBitmap(800, 600, Bitmap.Config.ARGB_8888);
        //Bind a canvas to it
        Canvas canvas = new Canvas(returnedBitmap);
        //Get the view's background
        Drawable bgDrawable = view.getBackground();
        if (bgDrawable != null) {
            //has background drawable, then draw it on the canvas
            bgDrawable.draw(canvas);
        } else {
            //does not have background drawable, then draw white background on the canvas
            canvas.drawColor(Color.WHITE);
        }
        // draw the view on the canvas
        view.draw(canvas);
        //return the bitmap
        return returnedBitmap;
    }catch (Exception e){
        Global.logError("getBitmapFromView", e);
    }
    return null;
}


public Uri getImageUri(Context inContext, Bitmap inImage) {
    try {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
        String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(),
                inImage, "", "");
        return Uri.parse(path);
    }catch (Exception e){
        e.getMessage();
    }
    return null;
}

我找到了解决方案

我已经更改了我的 getBitmapFromView 方法体

private Bitmap getBitmapFromView(LinearLayout view) {
    try {

        view.setDrawingCacheEnabled(true);

        view.measure(View.MeasureSpec.makeMeasureSpec(800, View.MeasureSpec.UNSPECIFIED),
                View.MeasureSpec.makeMeasureSpec(600, View.MeasureSpec.UNSPECIFIED));
        view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());

        view.buildDrawingCache(true);
        Bitmap returnedBitmap = Bitmap.createBitmap(view.getDrawingCache());

        //Define a bitmap with the same size as the view
        view.setDrawingCacheEnabled(false);

        return returnedBitmap;
    }catch (Exception e){
        Global.logError("getBitmapFromView", e);
    }
    return null;
}

一切正常 ;)

Answer 2

private Bitmap getBitmapFromView(LinearLayout view) {
    try {

        view.setDrawingCacheEnabled(true);

        view.buildDrawingCache();
        //Define a bitmap with the same size as the view
        Bitmap returnedBitmap = Bitmap.createBitmap(800, 600, Bitmap.Config.ARGB_8888);
        //Bind a canvas to it
        Canvas canvas = new Canvas(returnedBitmap);
        //Get the view's background
        Drawable bgDrawable = view.getBackground();
        if (bgDrawable != null) {
            //has background drawable, then draw it on the canvas
            bgDrawable.draw(canvas);
        } else {
            //does not have background drawable, then draw white background on the canvas
            canvas.drawColor(Color.RED);
        }
        // draw the view on the canvas
        view.draw(canvas);
        //return the bitmap
        return returnedBitmap;
    }catch (Exception e){
       // Global.logError("getBitmapFromView", e);
    }
    return null;
}
