ProgressDialog显示有关问题

ProgressDialog显示问题

@Override
public void onCreate(Bundle savedInstanceState) {
    // do all your other stuff here

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            mProgressDialog = ProgressDialog.show(YouTube.this.getApplicationContext(), "", YouTube.this.getString(R.string.loading), true);

            // start time consuming background process here
        }
    }, 1000); // starting it in 1 second
}

在1.6上有时候
mProgressDialog = ProgressDialog.show(this, "", getString(R.string.loading), true)
会出现错误 然后就在线程中加
