嗨，朋友们是安卓新手。我创建了一个包含 4 个选项卡的申请表，现在我需要一个布局的屏幕截图，如果它的编辑文本是在单击保存按钮时填充的。是否可以在android中做，如果不是任何格式，但我想要一个带有图像的字段副本

Calendar.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    //getScreenViewBitmap(vs);
    loadBitmapFromView(vs);
}
});
}
public static RelativeLayout createProgrammeView
(Context context, int width, int height, String title, String time) {
    RelativeLayout.LayoutParams params;


    RelativeLayout rlv = new RelativeLayout(context);
    params = new RelativeLayout.LayoutParams(width, height);
    rlv.setLayoutParams(params);
    rlv.setPadding(3, 3, 3, 3);
    //rlv.setBackgroundResource(R.drawable.background);


    TextView tv = new TextView(context);
    params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    params.addRule(RelativeLayout.ALIGN_PARENT_TOP);
    params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
    params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
    tv.setId(R.id.textView1);
    tv.setLayoutParams(params);
    tv.setGravity(Gravity.CENTER_VERTICAL);
    tv.setSingleLine(true);
    tv.setEllipsize(TruncateAt.END);
    tv.setTextColor(Color.parseColor("#fff"));
    tv.setTextSize(11);
    tv.setText(title);
    rlv.addView(tv);


    tv = new TextView(context);
    params = new RelativeLayout.LayoutParams(16, RelativeLayout.LayoutParams.WRAP_CONTENT);
    params.addRule(RelativeLayout.BELOW, R.id.textView1);
    params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
    params.setMargins(0, 4, 0, 0);
    tv.setId(R.id.time);
    tv.setLayoutParams(params);
    tv.setGravity(Gravity.CENTER_VERTICAL);
    tv.setSingleLine(true);
    tv.setEllipsize(null);
    tv.setTextColor(Color.parseColor("#fff"));
    tv.setTextSize(10);
    tv.setText(time);
    rlv.addView(tv);        

return rlv;
}
public static Bitmap loadBitmapFromView(RelativeLayout v) {
    Bitmap b = Bitmap.createBitmap(582, 136, Bitmap.Config.ARGB_8888);
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
      b.compress(Bitmap.CompressFormat.JPEG, 40, bytes);

        System.out.println(b);

        File f = new File(Environment.getExternalStorageDirectory()
                                + File.separator + "test1111.jpeg");
        FileOutputStream fo;

            try {
                fo = new FileOutputStream(f);
                fo.write(bytes.toByteArray());


                fo.close();
            } catch (FileNotFoundException e) {

                e.printStackTrace();
            } catch (IOException e) {

                e.printStackTrace();
            }
            System.out.println(f.exists());
    Canvas c = new Canvas(b);
    v.draw(c);
    return b;
}

嗨，在上面的代码中，它是一个相对布局，我尝试将布局输出作为图像，但它显示空的黑色图像没有任何内容，但它创建了一个文件。此外，当我单击时，布局视图也会发生变化

试试这个可能对你有帮助

 public static Bitmap loadBitmapFromView(View v) {
              Bitmap b = Bitmap.createBitmap( v.getWidth(), v.getHeight(), Bitmap.Config.ARGB_8888);                
              Canvas c = new Canvas(b);
              v.measure(v.getWidth(),v.getHeight());
              v.layout(0,0,v.getWidth(),v.getHeight());
              v.draw(c);
              return b;
        }
