Android - Can't get value from EditText inside Custom Dialog
提问by Alec Moore
I have been unsuccessful in getting the input from my EditText object inside my custom dialog.
我没有成功从我的自定义对话框中的 EditText 对象获取输入。
public class SetCityDialog extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LayoutInflater factory = LayoutInflater.from(MainActivity.this);
final View view = factory.inflate(R.layout.city_dialog, null);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Get the layout inflater
LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.city_dialog, null))
// Add action buttons
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int id) {
//This is the input I can't get text from
EditText inputTemp = (EditText) view.findViewById(R.id.search_input_text);
//query is of the String type
query = inputTemp.getText().toString();
newQuery();
getJSON newData = new getJSON();
newData.execute("Test");
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
SetCityDialog.this.getDialog().cancel();
}
});
return builder.create();
}
}
I don't get any exceptions, but the variable query is set to an empty string. Any help would be fantastic.
我没有得到任何异常，但变量查询设置为空字符串。任何帮助都会很棒。

I was trying to do the same thing and i get the same error. I don't no why. I already use AlertDialog.Builder in the past and get no trouble. But in your case change this code:
我试图做同样的事情，但我得到了同样的错误。我不知道为什么。我过去已经使用过 AlertDialog.Builder 并且没有遇到任何麻烦。但在您的情况下更改此代码：
public void onClick(DialogInterface dialog,
int id) {
//This is the input I can't get text from
EditText inputTemp = (EditText) view.findViewById(R.id.search_input_text);
//query is of the String type
query = inputTemp.getText().toString();
newQuery();
getJSON newData = new getJSON();
newData.execute("Test");
}
By this one:
通过这个：
public void onClick(DialogInterface dialog,
int id) {
Dialog f = (Dialog) dialog;
//This is the input I can't get text from
EditText inputTemp = (EditText) f.findViewById(R.id.search_input_text);
query = inputTemp.getText().toString();
...
}
This solution works for me and it seems to be the same for you. Found on stackoverflow
这个解决方案对我有用，对你来说似乎是一样的。在stackoverflow上找到

Use this instead :
改用这个：
View myLayout = nflater.inflate(R.layout.city_dialog, null);
EditText myEditText = (EditText) myLayout.findViewById(R.id.myEditText);
String valueOfEditText = myEditText.getText().toString();

No need to do that much coding. just change
不需要做那么多编码。只是改变
builder.setView(inflater.inflate(R.layout.city_dialog, null))
to
到
builder.setView(view)
and access text of EditText using **view.findView.....
并使用 **view.findView 访问 EditText 的文本.....
EditText inputTemp = (EditText) view.findViewById(R.id.search_input_text);
String xyz = inputTemp.getText().toString();

This is worked for me:
// if button is clicked, close the custom dialog
dialogButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
try {
Dialog inDialog = (Dialog) dialog;
EditText emailAddress = (EditText) inDialog.findViewById(R.id.emailAddress);
email = emailAddress.getText().toString();
if(email.length() == 0) {
objPublicDelegate.showToast("Please fill Email Address.");
}else{
objLoadingDialog.show("Please wait...");
// Call a network thread Async task
mNetworkMaster.runForgetAsync(email);
}
} catch (Exception e) {
e.printStackTrace();
}
}
});
