我的应用程序有一个相对布局的列表视图。现在我需要截取整个布局的屏幕截图，包括列表视图中可用的所有内容以及布局中显示的按钮和文本视图等其他内容。但是我的代码只占用了屏幕的可见部分。这里的视图是父布局。

public void screen(){

     View v1 = findViewById(R.id.screenRoot);

    rel.layout(0, 0, rel.getMeasuredWidth(),rel.getMeasuredHeight());    
    View v = v1.getRootView();
    v.setDrawingCacheEnabled(true);

   /* v.measure(MeasureSpec.makeMeasureSpec(w, w), 
            MeasureSpec.makeMeasureSpec(h, h));*/


//        v.layout(0, 0, rel.getWidth(), rel.getHeight());
    v.buildDrawingCache(true);

    System.out.println("rel "+rel.getHeight()+" "+v.getHeight());
    Bitmap b = v.getDrawingCache();  
    v.setDrawingCacheEnabled(false);
    String extr = Environment.getExternalStorageDirectory().toString();
    File myPath = new File(extr, "tiket"+".jpg");
    FileOutputStream fos = null;
    try {
        fos = new FileOutputStream(myPath);
        b.compress(Bitmap.CompressFormat.JPEG, 100, fos);
        fos.flush();
        fos.close();
        MediaStore.Images.Media.insertImage(getContentResolver(), b, "Screen", "screen");
        System.out.println("my path "+myPath+" "+fos);
    }catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    Toast.makeText(getApplicationContext(), "Image Captured Successfully", 0).show();

}

从您的 Click 事件或任何事情中调用 getBitmapFromView。R.id.root 是我的主要 RelativeLayout 所以你可以传递你的主要布局。

LayoutInflater inflater = (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
RelativeLayout root = (RelativeLayout)inflater.inflate(R.layout.youlayourfile,null);
root.setDrawingCacheEnabled(true);

Bitmap bmp = getBitmapFromView(this.getWindow().getDecorView().findViewById(R.id.root).getRootView());

URI uri = storPrintFile(bmp);

此函数返回布局的位图。现在您只需要将位图存储到您的设备和其他任何地方。

public Bitmap getBitmapFromView(View v) {
    v.setLayoutParams(new LayoutParams(
            RelativeLayout.LayoutParams.WRAP_CONTENT,
            RelativeLayout.LayoutParams.WRAP_CONTENT));
    v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
            MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
    v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
    Bitmap b = Bitmap.createBitmap(v.getMeasuredWidth(),
            v.getMeasuredHeight(), Bitmap.Config.RGB_565);

    Canvas c = new Canvas(b);
    v.draw(c);
    return b;       
}

将位图存储到设备中。

public URI storPrintFile(Bitmap bitmapToStore){
    ContextWrapper cw = new ContextWrapper(getApplicationContext());
    String path = cw.getDir("CapturedImages",Context.MODE_PRIVATE).getPath();
    File file = new File(path);
    boolean isFileCreated = false;
    if (!file.exists()) {
        isFileCreated = file.mkdir();
        System.out.println("Directory created in Internal Storage is :" + path);
    }
    String current = "Screen.jpg";//uniqueId.replace(" ", "-").replace(":", "-") + ".jpeg";
    System.out.println("Internal Storage path is : " + current);
    File mypath = new File(file, current);
    try {
        FileOutputStream out = new FileOutputStream(mypath);
        bitmapToStore.compress(Bitmap.CompressFormat.JPEG, 100, out);
        out.flush();
        out.close();

    } catch (Exception e) {
        e.printStackTrace();
    }
    return mypath.toURI();
}
