Android截屏并保存图片到本地

使用下面方法即可：

//截取屏幕
public void screenShort() {
    View dView = getWindow().getDecorView();
    dView.setDrawingCacheEnabled(true);
    dView.buildDrawingCache();
    Bitmap bitmap = Bitmap.createBitmap(dView.getDrawingCache());
    if (bitmap != null) {
        try {
            saveBitmap(bitmap);
        } catch (Exception e) {
        }
    }
}

//保存图片
private void saveBitmap(Bitmap bmp) throws IOException {
    File childFolder = Environment.getExternalStoragePublicDirectory(Environment
            .DIRECTORY_PICTURES);
    File imageFile = new File(childFolder.getAbsolutePath() + "/" + System.currentTimeMillis
            () + ".jpg");
    OutputStream fOut = new FileOutputStream(imageFile);
    bmp.compress(Bitmap.CompressFormat.JPEG, 60, fOut);//将bg输出至文件
    fOut.flush();
    fOut.close(); // do not forget to close the stream
    sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile
            (imageFile)));
    ToastUtils.showShort(getString(R.string.success));
}

记得添加权限~~~， 懒得抽出来，全都加上吧

    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.CAMERA" />
