Hide/Show TextView when touching button inside a Fragment

Hide/Show TextView when touching button inside a Fragment - java

So I am here asking for your kind help.
I am trying to make a TextView visible and gone by touching a single button.
It did work inside a MainActivityJava but when doing the same inside a Fragment Activity, I am facing many troubles.
It seems that the setOnClickListener does not match with fragment but I do not know how to deal with it...

Button button = getActivity().findViewById(R.id.buttonTaureauBrute);
TextView textView = getActivity().findViewById(R.id.textView3);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
textView.setVisibility(View.GONE);
textView.setVisibility(View.VISIBLE);

Invoking findViewById on a null object. Which isn't null

So I have a settings fragment which contains, well, settings.
On line 22 I have a findview which finds a textview. It worked wonders until today (Didn't change a thing). Now I imagine it will also fail the rest of the finds but since it crashes on this one, we will never know.
Why is that?

You need to do on the first line of onCreateView:
View view = inflater.inflate(R.layout.settings, container, false);
Then do for each of your findViewById:
view.findViewById(R.id.your_view);
You're inflating the view last instead of first.
Then at the end of onCreateView():
return view;

Please try below way to initialize and return in your oncreateview
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState){
View view = inflater.inflate(R.layout.settings, container, false);
//Init all here like
accSettings = (TextView) view. findViewById(R.id.SettingsFragmentAccountSettings)
//and then return like
return view;
}
Hope it may help you

Hello, I want to show the data I got from json in my android project in the search layout section, but the data is not visible. Can you help me?

You are retrieving your data in your main activity and sending the data through your intent
intent.putExtra("city", country.getText().toString()); intent.putExtra("temp",temp.getText().toString());
However, you are not fetching the data that you sent through intent in your fragment.
You have to fetch them according to the key values by which you sent.
In your onCreateView() in your fragment, you can fetch each data you sent through your intent in the form:
String city = getArguments().getString("city");

Thanks in Advance.

In this case the reason may be in StateDataItemBinding.
Is your root view in state_data_item.xml is clickable?

EditText autoscroll doesn't work after showing dialog

I'm developing an app for users to share their books. To achieve this, I'm getting different data about the book from the user. The problem is, horizontal autoscrolling of all EditTexts are working until Dialog has been shown and dismissed. Once a dialog has been dismissed on the fragment, horizontal autoscrolling of the EditText's on this layout won't work.
I added:
android:focusable="true"
android:focusableInTouchMode="true"
to parent layout of the edittext but doesn't work.
Also to make sure that autoscrolling is enabled I've added:
android:scrollHorizontally="true"
But none of above helped.
Here is XML code of the fragment layout.

UI Design and Dialog
In the image above, there are EditTexts Name Of Book and Name of Author. Before showing a dialog, both of them work like a charm. When writing something, the cursor automatically scrolls to the end. Once Dialog has been shown and dismissed, none of them works properly, and the cursor stays at the end of the EditText but still the characters are being written continues in the hidden part.
In this UI it cannot be seen because of the issue, but I've written.

Weird buggy layout UI image
Please, help me to solve this problem. Thanks in advance.

As a solution, I don't know the underlying reason, but the problem solved once I removed Butterknife library from my project.

Now my Fragment.java
package com.wny.wecare.fragment;
import android.app.Fragment;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.ImageView;
import com.wny.wecare.R;
public class AboutUsFragment extends Fragment implements OnClickListener {
public static final String TAG = AboutUsFragment.class.getSimpleName();
private View mRootView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mRootView = inflater.inflate(R.layout.fragment_about_us, container, false);
return mRootView;
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
ImageView Img = (ImageView) getView().findViewById(R.id.img_indicator);
Img.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://infinitycodeservices.com")));
}
});
}
}

do this rather bro
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
ImageView Img = (ImageView) getView().findViewById(R.id.img_indicator);
if(v == img)
Context.startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("http://infinitycodeservices.com"))); //context stands 4 ur activity
}
Edit 1: i change the intent to Intent this was the reason for the earlier variable error..
so retry & seee
let me know if it works.. im feeling i left something.

According to my understanding, your public void onClick(View v) not called you just declare but don't set Listener,then when you set listener to ImageView on onClick() that never call too.
I think you should setListener() in onCreateView() by using anonymous inner class like this
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mRootView = inflater.inflate(R.layout.fragment_about_us, container, false);
ImageView Img = (ImageView) getView().findViewById(R.id.img_indicator);
Img.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://infinitycodeservices.com")));
}
});
return mRootView;
}
or If you still use implement View.OnClickListener() use this
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mRootView = inflater.inflate(R.layout.fragment_about_us, container, false);
ImageView Img = (ImageView) getView().findViewById(R.id.img_indicator);
Img.setOnClickListener(this);
return mRootView;
}
#Override
public void onClick(View v) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://infinitycodeservices.com")));
}
Hope this helps

After Hours of reading i finally solved this issue.
Thanks to this link Correct way to call onClickListener on fragments
Thank You all for your help, very appreciated.
Here is my full AboutUsFragment.Java
package com.wny.wecare.fragment;
import android.app.Fragment;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.ImageButton;
import android.widget.ImageView;
import com.wny.wecare.MainActivity;
import com.wny.wecare.R;
public class AboutUsFragment extends Fragment implements OnClickListener {
ImageView Contact;
ImageView Facebook;
ImageView Google;
ImageView Website;
ImageView Rate;
ImageView Apps;
public static final String TAG = AboutUsFragment.class.getSimpleName();
private View mRootView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View mRoot = inflater.inflate(R.layout.fragment_about_us, null);
Contact = (ImageView) mRoot.findViewById(R.id.contact_icon);
Contact.setOnClickListener(this);
Facebook = (ImageView) mRoot.findViewById(R.id.facebook_icon);
Facebook.setOnClickListener(this);
Google = (ImageView) mRoot.findViewById(R.id.google_icon);
Google.setOnClickListener(this);
Website = (ImageView) mRoot.findViewById(R.id.website_icon);
Website.setOnClickListener(this);
Rate = (ImageView) mRoot.findViewById(R.id.rate_icon);
Rate.setOnClickListener(this);
Apps = (ImageView) mRoot.findViewById(R.id.apps_icon);
Apps.setOnClickListener(this);
return mRoot;
}
#Override
public void onClick(View v) {
switch (v.getId()){
case R.id.contact_icon:
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("mailto:infinitycodeservices#gmail.com")));
break;
case R.id.facebook_icon:
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://facebook.com/infinitycodeservices")));
break;
case R.id.google_icon:
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://plus.google.com/105796163192090141980/")));
break;
case R.id.website_icon:
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://infinitycodeservices.com")));
break;
case R.id.rate_icon:
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/developer?id=InfinityCodeServices")));
break;
case R.id.apps_icon:
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/developer?id=InfinityCodeServices")));
break;
}
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
Intent intent;
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
String cameback="CameBack";
intent = new Intent(getActivity(), MainActivity.class);
intent.putExtra("Comingback", cameback);
startActivity(intent);
return true;
}
return false;
}
}

You are in a Fragment so I think you should invoke startActivity() method using:
getActivity().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://infinitycodeservices.com")));
