[英]Android AlertDialog how to disable buttons before showing?
如何在顯示警告對話框之前禁用按鈕,就像在Fatal對話框中完成一樣"Android error: The application has stopped unexpectedly please try again"
。
我用這樣的例子:
@Override
protected Dialog onCreateDialog(int id) {
if (id == DIALOG) {
Log.d(LOG_TAG, "Create");
AlertDialog.Builder adb = new AlertDialog.Builder(this);
adb.setTitle("Title");
adb.setMessage("Message");
adb.setPositiveButton("OK", null);
dialog = adb.create();
dialog.setOnShowListener(new OnShowListener() {
public void onShow(DialogInterface dialog) {
Log.d(LOG_TAG, "Show");
}
});
dialog.setOnCancelListener(new OnCancelListener() {
public void onCancel(DialogInterface dialog) {
Log.d(LOG_TAG, "Cancel");
}
});
dialog.setOnDismissListener(new OnDismissListener() {
public void onDismiss(DialogInterface dialog) {
Log.d(LOG_TAG, "Dismiss");
}
});
return dialog;
}
return super.onCreateDialog(id);
}
public void onclick(View v) {
showDialog(DIALOG);
}
如果我在dialog.setOnShowListener上啟用按鈕,則用戶可以在“確定”按鈕上單擊兩次。
AlertDialog.Builder alertbox = new AlertDialog.Builder(this);
//...All your code to set up the buttons initially
AlertDialog dialog = alertbox.create();
Button button = dialog.getButton(AlertDialog.BUTTON_NEUTRAL);
if(monsterint > playerint)
{
button.setEnabled(false);
}
使用getButton啟用和禁用
我認為你應該默認禁用它。 並使用onShowListener()如下:
dlg.setOnShowListener(new OnShowListener() {
@Override
public void onShow(DialogInterface dialog) {
// TODO Auto-generated method stub
//Enable buttons..
}
});
