我目前遇到了向父母添加視圖的問題。我不知道如何解決這個問題。我曾看過其他答案，但是沒有任何能夠幫助我。指定的孩子已經有父母異常錯誤
這裏是我的代碼：
int countdown = 0;
CountDownTimer mCountDownTimer;
TableRow tr1;
TableRow tr2;
TextView tv;
protected void createNullUI() {
tr1 = new TableRow(getBaseContext());
tr2 = new TableRow(getBaseContext());
tv = new TextView(this);
tv.setText("Ooops, it looks like the user you were searching for does not exist... You will be redriced back to our homepage shortly =)");
tv.setMaxLines(2);
tv.setTextSize(30);
tv.setSingleLine(false);
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final ProgressBar mProgressBar = (ProgressBar) inflater.inflate(R.layout.progress, null, false);
mProgressBar.setProgress(countdown);
runOnUiThread(new Runnable() {
public void run() {
//set up the count down timer
mCountDownTimer = new CountDownTimer(3000, 1000) {
@Override
public void onTick(long millisUntilFinished) {
Log.v("Log_tag", "Tick of Progress" + countdown
+ millisUntilFinished);
countdown++;
mProgressBar.setProgress(countdown);
}
@Override
public void onFinish() {
countdown++;
mProgressBar.setProgress(countdown);
}
};
mCountDownTimer.start();
TableLayout.LayoutParams tableRowParams = new TableLayout.LayoutParams(
TableLayout.LayoutParams.MATCH_PARENT,
TableLayout.LayoutParams.WRAP_CONTENT);
tr1.setLayoutParams(tableRowParams);
tr2.setLayoutParams(tableRowParams);
tr1.addView(tv);
tr2.addView(mProgressBar);
((ViewGroup)tr1.getParent()).removeView(tr1);
((ViewGroup)tr2.getParent()).removeView(tr2);
tableScrollView.addView(tr1); // <--- Error here
tableScrollView.addView(tr2);
}
});
}

全班有助於 – 2014-08-30 04:24:31
@Rod_Algonquin確定將在早上做。這是否有助於圖標即使被替換爲其他圖像也不會改變？ – gedr 2014-08-30 04:30:20
@Rod_Algonquin好的，我添加了全班。另外，如果它有幫助，當我保存並運行應用程序時，它說它已被部署，並且不需要重新安裝（？）。我不知道這是否會影響到它，我也想問問你是否知道解決方法。 – gedr 2014-08-30 17:29:49
