The method of setting up monitoring events in the head of NavigationView is for your reference. The specific content is as follows
1. Delete static import and delete in XML:
<
android:
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start" />
<!--Delete the following two lines-->
<!--app:headerLayout="@layout/nav_header"-->
<!--app:menu="@menu/nav_menu"-->
2. FindViewById in the code and findViewById, then introduce the header and menu, then get the header layout, and finally set the listening event:
//findviewbyid navigationView = (NavigationView) findViewById(.nav_view); //Introduce header and menu(.nav_header); (.nav_menu); //Get the head layoutView navHeaderView = (0);
3. The complete code is as follows:
private void initNavigation() {
drawerLayout = (DrawerLayout) findViewById(.drawer_layout);
navigationView = (NavigationView) findViewById(.nav_view);
//Introduce header and menu (.nav_header);
(.nav_menu);
//Set menu's listening event (new () {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (()) {
case .add_city:
//start up startActivityForResult(new Intent(, ),
REQUEST_CODE_PICK_CITY);
();
break;
case :
Intent SettingIntent = new Intent(, );
startActivity(SettingIntent);
();
break;
case :
Intent aboutIntent = new Intent(, );
startActivity(aboutIntent);
();
break;
}
return false;
}
});
//Get the head layout View navHeaderView = (0);
//Set the listening event icon_image = (CircleImageView) (.icon_image);
icon_image.setOnClickListener(new () {
@Override
public void onClick(View view) {
();
}
});
//Read the avatar (this, icon_image);
//dialog
dialog = new CustomDialog(this, 100, 100, .dialog_photo, .Theme_dialog,
, .pop_anim_style);
//Off-screen click is invalid (false);
btn_camera = (Button) (.btn_camera);
btn_camera.setOnClickListener(new () {
@Override
public void onClick(View view) {
toCamera();
}
});
btn_picture = (Button) (.btn_picture);
btn_picture.setOnClickListener(new () {
@Override
public void onClick(View view) {
toPicture();
}
});
btn_cancel = (Button) (.btn_cancel);
btn_cancel.setOnClickListener(new () {
@Override
public void onClick(View view) {
();
}
});
}
