当我想在单击编辑按钮时显示alertdialog时，我一直收到异常。当我注释掉alertDialog.show（）时，该应用程序可以正常工作，否则会崩溃。请告诉我错误的位置。我真的很感激解释。
例外是：

我的活动代码，其中edtEdit onClick不起作用：
public class Income extends AppCompatActivity {
TextView edtTextMonth , edtTextTitle, edtTextDate, edtTextIncome;
TableLayout tableLayoutDisplay;
ImageButton btnNext, btnPrev, btnEdit;
DBHelper myDB;
int monthNumber = 12, year = 1964;
String monthName, prevNext;
String T1, T2, T3; // selected row values
int activity = 0, tr; // '0' as an IncomeActivity in DBHelper insertData method.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_income);
myDB = new DBHelper(this);
edtTextMonth = (TextView) findViewById(txtViewMonth);
edtTextDate = (EditText) findViewById(R.id.editTextDate);
edtTextTitle = (EditText) findViewById(R.id.editTextTitle);
edtTextIncome = (EditText) findViewById(R.id.editTextIncome);
btnNext = (ImageButton) findViewById(R.id.btnNext);
btnPrev = (ImageButton) findViewById(R.id.btnPrev);
btnEdit = (ImageButton) findViewById(R.id.btnEdit);
}
public void editIncomeValues(View view) {
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(Income.this);
alertDialogBuilder.setTitle("Edit");
alertDialogBuilder.setMessage("Are you sure, You wanted to make decision");
alertDialogBuilder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface arg0, int arg1) {
edtTextTitle.setText(T1);
edtTextDate.setText(T2);
edtTextDate.setText(T3);
edtTextTitle.requestFocus();
}
})
.setNegativeButton("No",new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
}
}
答案 0 :(得分：1)
您无需创建AlertDialog只需删除此行：
AlertDialog alertDialog = alertDialogBuilder.create();
并将最后一行更改为：
alertDialogBuilder.show();

我看到点击“editIncomeValues（）”会在你显示对话框的地方调用。
我猜您面临的问题是因为您已为警报对话框设置了操作 - alertDialogBuilder 并在新对话框上执行了显示 - alertDialog 。
您的代码非常完美。只是改变不要创建另一个alertDialog（alertDialog）并使用相同的创建（alertDialogBuilder）来显示...
