Android 將View轉換成BitMap

有時候我們需要將一個佈局文件轉換成圖片。

   工具代碼

 //把佈局變成Bitmap
	private Bitmap getViewBitmap(View addViewContent) {

	addViewContent.setDrawingCacheEnabled(true);

	addViewContent.measure(
	View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),
	View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
	addViewContent.layout(0, 0,
	addViewContent.getMeasuredWidth(),
	addViewContent.getMeasuredHeight());

	addViewContent.buildDrawingCache();
	Bitmap cacheBitmap = addViewContent.getDrawingCache();
	Bitmap bitmap = Bitmap.createBitmap(cacheBitmap);

	return bitmap;
	}

佈局文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <TextView
        android:paddingLeft="5dp"
        android:paddingRight="5dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/wb_location_map_marker_name"
        android:background="#FFFFFF"
        android:text="李三" />

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/jy_icon_gcoding" />

</LinearLayout>

使用操作記錄

LayoutInflater inflater = getLayoutInflater();
		View view=inflater.inflate(R.layout.wb_location_map_marker,null);
		TextView txt=(TextView)view.findViewById(R.id.wb_location_map_marker_name);
		txt.setText(content);
		Bitmap viewBitmap=getViewBitmap(view);
