使用textView将drawable保存到Gallery中

我有一个名为tmp1的drawable，它在imageView上设置。

final ImageView blankcard= (ImageView) findViewById(R.id.blankcard); 

blankcard.setBackgroundResource(R.drawable.tmp1);

我将一些从editText中获取的文本设置为tmp1到Intent：

stv1.setText(Name+" ");
stv2.setText(Company);
stv3.setText("  "+Phone);
stv4.setText(Mobile+" ");
stv5.setText("  "+Address);
stv6.setText("  "+Email);
stv7.setText(Website+"  ");
stv8.setText(Title+" ");

crdlogoframe.setImageBitmap(BitmapFactory.decodeFile(pre_img_path1));
crdqrframe.setImageBitmap(BitmapFactory.decodeFile(pre_img_path2));

为了将.tmp1保存到我的图库中，我将其转换为Bitmap并保存目录。然后我有：

Bitmap icon = BitmapFactory.decodeResource(context.getResources(),R.drawable.tmp1);
try {
FileOutputStream out = new FileOutputStream(Environment.getExternalStorageDirectory()+ "/Android/data/MapCards/templates.jpg/");
icon.compress(Bitmap.CompressFormat.PNG, 90, out);
out.close();
} catch (Exception e) {
e.printStackTrace();
}

Toast.makeText(getApplicationContext(), "Saved Directory!", Toast.LENGTH_SHORT).show();

这有助于我只将drawable保存到文件夹中。有没有办法用文本保存它，也可能是图像。感谢。

这是布局：

我如何嵌套画布：

public class Template extends Activity {

FrameLayout frame;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.template);

frame  = (FrameLayout)findViewById(R.id.frame); 
context=this;

final ImageView blankcard= (ImageView) findViewById(R.id.blankcard);

btn1.setOnLongClickListener(new OnLongClickListener() {

        @Override
        public boolean onLongClick(View arg0) {

             frame.setDrawingCacheEnabled(true);
             frame.buildDrawingCache(true);
             Bitmap bmpText = Bitmap.createBitmap(frame.getDrawingCache());
             Canvas canvas = new Canvas(bmpText);
             Paint p = new Paint();
             canvas.drawText("Hi I am Here", 25, 25, p);
             frame.draw(canvas);
             canvas.save();
             frame.setDrawingCacheEnabled(false);

             try {
                   FileOutputStream out = new FileOutputStream(Environment.getExternalStorageDirectory()+ "/Android/data/MapCards/templates.jpg/");
                   bmpText.compress(Bitmap.CompressFormat.PNG, 90, out);
                   out.close();
                } catch (Exception e) {
                   e.printStackTrace();
                }


            Toast.makeText(getApplicationContext(), "Saved Directory!", Toast.LENGTH_SHORT).show();
            return false;
        }
});

具有FrameLayout的新活动：

public class SaveCard extends Activity{

FrameLayout frame;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.savecard);

    frame  = (FrameLayout)findViewById(R.id.frame);

}}

新框架布局：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/frame"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.8" >

<TextView
    android:id="@+id/selected"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text= "Hi I am Here"
     />

<ImageView
    android:id="@+id/image_view"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:adjustViewBounds="true"
    android:scaleType="matrix" />
</FrameLayout>

上次错误：不幸的是，MapCard已经停止：当我长按按钮时。

logcat的：
