我在 alertDialog 中有一个 textView,我想在用户单击 Ok 按钮时获取此文本...
但是我不知道如何实现它?(在 google android developer 中没有解释)
这是我的 forgot_password_popup.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="@null" >
<ImageView
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_weight="0.76"
android:background="#FFFFBB33"
android:contentDescription="@string/app_name"
android:scaleType="center"
android:src="@drawable/logo" />
<EditText
android:id="@+id/emailText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="4dp"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:layout_marginTop="16dp"
android:hint="Enter Email Address"
android:inputType="textEmailAddress" />
</LinearLayout>
这是我更新的课程:
public class LoginDialogFragment extends DialogFragment {
private EditText emailText;
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Get the layout inflater
LayoutInflater inflater = getActivity().getLayoutInflater();
final View v = inflater.inflate(R.layout.forgot_password_popup, null);
emailText = (EditText) v.findViewById(R.id.emailText);
// Inflate and set the layout for the dialog
// Pass null as the parent view because its going in the dialog layout
builder.setView(inflater.inflate(R.layout.forgot_password_popup, null))
// Add action buttons
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
try {
String email=emailText.getText().toString();
ParseUser.requestPasswordReset(email);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
LoginDialogFragment.this.getDialog().cancel();
}
});
return builder.create();
}
}
这是 logcat(你可以看到它写了无效的电子邮件,因为电子邮件是空的):
