这是我的 Android代码。我在下面的行 Toast 中有错误上面写着“Unreachable Statement”，我知道这个错误来自 return我的If但是不知道怎么解决
错误部分:
do
{
return;
if ((paramAnonymous2Int == 0) && (AndroidHTMLActivity.this.Count == 4))
{
Toast.makeText(getApplicationContext(),"نسخه رایگان",Toast.LENGTH_SHORT).show();
return;
}
}
整个函数:
@JavascriptInterface
public void SaveDialog(final String paramString)
{
final SQLiteDatabase mydatabase = openOrCreateDatabase("CopyCollection", MODE_PRIVATE, null);
Object localObject = mydatabase.rawQuery("SELECT * FROM Details WHERE ID=" + paramString + ";", null);
if (((Cursor)localObject).moveToFirst()) {
do
{
AndroidHTMLActivity.this.appName = ((Cursor)localObject).getString(1);
AndroidHTMLActivity.this.txtClip = ((Cursor)localObject).getString(2);
AndroidHTMLActivity.this.text_Date = ((Cursor)localObject).getString(3);
} while (((Cursor)localObject).moveToNext());
}
localObject = new AlertDialog.Builder(AndroidHTMLActivity.this);
((AlertDialog.Builder)localObject).setTitle("ذخیره");

最佳答案
看这段代码
return;
if ((paramAnonymous2Int == 0) && (AndroidHTMLActivity.this.Count == 4))
你在验证之前返回，因此永远不会到达它。
