原标题:Creating a Bitmap of a View

我试图通过激化布局,以图谋划策。

View marker = ((LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.overlay_view, null);

Now i want to convert this View to a Bitmap:

public static Bitmap createDrawableFromView(Context context, View view){
        DisplayMetrics displayMetrics = new DisplayMetrics();
        ((Activity)context).getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);

        view.measure(displayMetrics.widthPixels, displayMetrics.heightPixels);
        view.layout(0, 0, displayMetrics.widthPixels, displayMetrics.heightPixels);

        Bitmap cache = Bitmap.createBitmap(view.getMeasuredWidth(), view.getMeasuredHeight(), Bitmap.Config.ARGB_8888);

        Canvas canvas = new Canvas(cache);
        view.draw(canvas);

        return cache;
    }

I also tried measure(1, 1) and layout(0 ,0 ,0 ,0) without any changes. The Bitmap looks like the filled layout. Now the Problem: If i put something into the View thats makes the View bigger than the Displaysize in width or height (example: a TextView with a long text), the Bitmap is also bigger. The Views XML width and height is WRAP_CONTENT but it didnt works. I never put this View somewhere to display it (becouse i only need the Bitmap).

问题:怎样才能将妇女权利行动纳入到最高范围:显示Width?

我尝试了意见。 我真心要理解所发生的事情,那是孤立布局,确定观点的内容。

这一观点:正如我所显示的那样,我们总是会更大吗? (如果在其中增加部分)

这里是《拉伊特》的一个实例:

<RelativeLayout android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/somedrawable"
        android:padding="10dp"
        android:clickable="true">
        <TextView android:id="@+id/name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Name"/>
        <TextView android:id="@+id/description"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@id/name"
            android:text="Description"
            android:textSize="20dp"
            android:textColor="#ffffff"/>
    </RelativeLayout>
最佳回答

我找到了解决办法:

第一步:增加新的LayoutParams。 这一点很重要,如果你得不到Null Pointer的话,就不予以认可。

view.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

Second:

view.measure(MeasureSpec.makeMeasureSpec(displayMetrics.widthPixels), MeasureSpec.AT_MOST),
             MeasureSpec.makeMeasureSpec(displayMetrics.heightPixels, MeasureSpec.AT_MOST));

www.un.org/spanish/ga/president 第一个参数是显示宽度或超度,第二个参数是AT_MOST,这是“消除”观点所需要的。

成就美好! (关于我:p)
