问题描述

我想拍摄当前屏幕的屏幕快照，单击一个按钮.任何人都可以提供一个android代码.我也需要将图像保存在图库中.这就是我尝试过的

I want to take the screen shot of current screen when,I click a button.Can anyone provide a android code.I need to save the image in the gallery also.this is what i tried

public class CaptureScreenShots extends Activity {
LinearLayout L1;
ImageView image;
 @Override
     protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.screen_shots);
    L1 = (LinearLayout) findViewById(R.id.LinearLayout01);
    Button but = (Button) findViewById(R.id.munchscreen);
    but.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            View v1 = L1.getRootView();
            v1.setDrawingCacheEnabled(true);
            Bitmap bm = v1.getDrawingCache();
            BitmapDrawable bitmapDrawable = new BitmapDrawable(bm);
            image = (ImageView) findViewById(R.id.screenshots);
            image.setBackgroundDrawable(bitmapDrawable);
        }
    });
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.screen_shots, menu);
    return true;
}

}

推荐答案

private void getScreen(){
View v = view.getRootView();
v.setDrawingCacheEnabled(true);
Bitmap b = v.getDrawingCache();
String extr = Environment.getExternalStorageDirectory().toString();
File myPath = new File(extr, getString(R.string.free_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");
} catch (FileNotFoundException e) {
   e.printStackTrace();
} catch (Exception e) {
   e.printStackTrace();

}
