DialogFragment Usage & click to listen

 

/* DialogFragment is a pop-up box for displaying an interface on the Activity, such as an input box, a warning box, and a confirmation box.
* DialogFragment separately sets the layout XML file
* To use DialogFragment, at least the onCreateView or onCreateDIalog method must be implemented;
* OnCreateView: displays the Dialog using the defined xml layout file.
* OnCreateDialog: You can use AlertDialog or Dialog to create a Dialog.
*/

Below are some examples I have written myself:

1. Modify the name input box

Layout file:

1. Enter the EditBox control to enter the new user name.

2. Confirm the ImageView and click monitor to obtain the input characters.

3. The exit Button is not modified.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:orientation="vertical">    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="horizontal">        <EditText            android:layout_width="0dp"            android:layout_weight="1"            android:layout_height="match_parent"            android:hint="Please enter new user name ..."            android:inputType="text"            android:id="@+id/opponent_name_edit"/>        <ImageView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:background="@drawable/ic_edit"            android:id="@+id/opponent_name_confirm"/>    </LinearLayout>    <Button        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="BACK"        android:textSize="24sp"        android:layout_marginTop="10dp"        android:id="@+id/edit_dialog_back"/></LinearLayout>

 

2. Click box for Content Selection

 

/* DialogFragment activity settings are the same as general Fragment settings.
* I generally use the onCreateView method.
*/

public class EditDialogue extends DialogFragment {    private EditText mNewNameEditText;    private ImageView mNewNameConfirm;    private String player;    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){        View rootView =inflater.inflate(R.layout.opponent_name_edit,container);        mNewNameEditText = (EditText) rootView.findViewById(R.id.opponent_name_edit);        mNewNameConfirm = (ImageView) rootView.findViewById(R.id.opponent_name_confirm);        Button backButton = (Button) rootView.findViewById(R.id.edit_dialog_back);        backButton.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                player="";                dismiss();            }        });

　　　　mNewNameConfirm.setOnClickListener(new View.OnClickListener() {
    　　　　@Override
   　　　　 public void onClick(View v) {
        　　　　player = mNewNameEditText.getText().toString();
       　　　　 setData();dismiss();
   　　　　 }});

　　　　return rootView;    }}

 

/* Click Detection
* You can set the Onclick attribute in the XML file by clicking a button to directly call the MainActivity method.
*/

anroid:OnClick="RecordName"

// Set the function in Activity

Public void RecordName (View view) {EditBox editbox = findViewById (R. id. name_edit); String newName = editbox. getText (). toString (); // here getText () is obtained as Editable type, toString () Conversion}

/* Click Detection
* In Fragment, OnclickLisener is used for listening.
* OnclickLisener is a function of the View class. Therefore, it can be used for buttons and controls inherited from the View class.
* The input box also listens to the ImageView and sends data to close the Dialog
*/

mNewNameConfirm.setOnClickListener(new View.OnClickListener() {    　　　　@Override   　　　　 public void onClick(View v) {        　　　　player = mNewNameEditText.getText().toString();       　　　　 setData();dismiss();   　　　　 }});
