Fragment overlapping another fragment instead of replacing it

Fragment overlapping another fragment instead of replacing it - java

The setup I have is a main_activity fragment that just has welcome text, and when you tap the start button, it's supposed to switch fragments. Instead of replacing the current fragment, it just overlays it on top of the main_activity fragment and won't allow me to perform the action associated with the new fragment.
Main Activity example
quote_fragment overlapping main activity

Don't replace your top-level view group. Create an empty frame layout inside of the top-level frame layout and use that as the ID to replace.
If you have elements in the main layout you no longer want visible you'll have to hide them (or use a fragment to show them in the first place which will get replaced).

fragments and bottomNavigationView

enter image description hereI'm totally new in android studio and java.
I created one bottomNavigation for my app and I used 3 fragments and it's totally fine and working.
but now I want to add one seekBar and click listener on one of my fragments but I couldn't do it.
my question is in which life cycle view or function I have to add this seek bar click listener?
I want to add this code as a seekbar listener
seekBar.findViewById(R.id.seekBar);
textView.findViewById(R.id.textView3);
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
textView.setText(progress+"/100");
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});

For this, you actually need separate java files that, in the class declaration, extends 'Fragment'. This is a really good youtube video for it:

Hope this helps.

Imageview to VideoView using fragment

I am trying to make an app with navigation drawer using fragment, where on the home screen there should be images and when you click the image it should take you to that particular image's fragment and video starts playing. But unfortunately I can't see any image on the home screen (maybe I am making mistake in layout). Please help me out. Thanks in advance.

You have created findViewById function in on create which returns 0.
You need a video reference from layout which you are inflating.
Something similar to this.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_first, container, false);
// see the difference

v1.setVideoURI(Uri.parse("https://myvideo.mp4"));

Add an OnclickListener to the holder.text_number:
String message = "";
holder.text_number.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
message = textview.getText().toString();
Toast.makeText(getActivity(), "Message : " + message, Toast.LENGTH_LONG).show();
}
});
Now do whatever you want with the message String.

final TextView text_number2=(TextView)view.findViewById(R.id.text_calllog_number);
holder.text_number.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText( context, "" + text_number2.getText().toString() , Toast.LENGTH_LONG).show();
}
});

Can someone can help me please,
many thnaks

First you need to attach the fragments to activity then you can simply define two strings String one ,String two in the activity containing the fragments and assign the value of each editText to diffrent one
i.e
String one=editTextOne.getText.toString();
String two=editTextTwo.getText.toString();

When you have to switch between either activities or fragments, you can use Shared Preferences to store a small amount of datas and retrieve them.
Shared Prefs are small sets of key/value pairs.
Write
SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.();
editor.putInt(getString(R.string.saved_high_score), newHighScore);
editor.commit();
Read
SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
int defaultValue = getResources().getInteger(R.string.saved_high_score_default);
long highScore = sharedPref.getInt(getString(R.string.saved_high_score), defaultValue);
You can write and read any primitive data types such as Strings using put[Type] and get[Type] methods.
Source codes above come from the official android developer training and belongs to Android.
"is there a way with saveInstanceState ?"
I think this bundle is usefull when one activity is destroyed and created by Screen rotation or resumed after a call, but not when switching between activities and fragments.
But you can try it. I know that views like EditText with id have a built-in saveInstanceState so you do not have to handle it manually.
To switch between fragments you can use activity class scoped properties. You will need to add interfaces to your fragments to allow them to communicate with the activity.
EXAMPLE
The following example shows how to switch between fragments and keep EditText values.
The MainActivity contains a FrameLayout and two buttons. The fragment transaction is done on button click events.
Fragments include an interface to communicate with the activity. Each time the EditText value is changed, the activity's property is updated.
The activity communicates with the fragment to set EditText value right after the transaction.
First of all, here are xml layouts files for the MainActivity, the FragmentA and the FragmentB classes :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="100"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="morbak.stackoverflow.fragmentcommunication.MainActivity">

<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="50"
android:orientation="horizontal"
android:weightSum="100">
<Button
android:id="#+id/button1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="50"
android:text="Fragment A" />
<Button
android:id="#+id/button2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="50"
android:text="Fragment B" />
</LinearLayout>
</LinearLayout>
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:id="#+id/etOne"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Fragment A content"/>
</LinearLayout>
fragment_a.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:id="#+id/etTwo"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Fragment B content"/>
</LinearLayout>
fragment_b.xml
Then, here are Fragments A and B classes. Source code is self explanatory.
package morbak.stackoverflow.fragmentcommunication;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.EditText;
public class FragmentA extends Fragment {
//Views
EditText etOne;
//Fields
String value;
//Listeners
OnFragmentASelectedListener mCallback;
//Context
Context context;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//Inflate views and layouts
View rootView = inflater.inflate(R.layout.fragment_a, container, false);
etOne = (EditText) rootView.findViewById(R.id.etOne);
//Events
etOne.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
//Execute the interface's abstract method
mCallback.onFragmentASelected(s.toString());
}
#Override
public void afterTextChanged(Editable s) {
}
});
etOne.setText(value);
return rootView;
}
//Set the fragment's field value
public void setEditText(String newValue) {
value = newValue;
}
//Interface
public interface OnFragmentASelectedListener {
public void onFragmentASelected(String value);
}
//Throws an exception if the activity implements FragmentA.OnFragmentASelectedListener, but not the abstract method
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
context = activity;
// This makes sure that the container activity has implemented
// the callback interface. If not, it throws an exception
try {
mCallback = (OnFragmentASelectedListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ " must implement OnFragmentASelectedListener");
}
}
}
FragmentA.java
The same work should be done with FragmentB, but you obviously have to search and replace FragmentA to FragmentB and etOne to etTwo.
Finally, here is the MainActivity who handles fragment transactions and uses fragments' listeners :
package morbak.stackoverflow.fragmentcommunication;
import android.content.Context;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity implements FragmentA.OnFragmentASelectedListener, FragmentB.OnFragmentBSelectedListener {
Button button1;
Button button2;
FragmentTransaction transaction;
FragmentA fragmentA;
FragmentB fragmentB;
String editTextOne;
String editTextTwo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button1 = (Button) findViewById(R.id.button1);
button2 = (Button) findViewById(R.id.button2);
editTextOne = "";
editTextTwo = "";
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
transaction = getSupportFragmentManager().beginTransaction();
fragmentA = new FragmentA();
transaction.replace(R.id.fragment_container, fragmentA);
transaction.addToBackStack(null);
transaction.commit();
fragmentA.setEditText(editTextOne);
}
});
button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
transaction = getSupportFragmentManager().beginTransaction();
fragmentB = new FragmentB();
transaction.replace(R.id.fragment_container, fragmentB);
transaction.addToBackStack(null);
transaction.commit();
fragmentB.setEditText(editTextTwo);
}
});
}
public void onFragmentASelected(String value) {
editTextOne = value;
}
public void onFragmentBSelected(String value) {
editTextTwo = value;
}
}
MainActivity.java

Fragment being displayed, overlaps current fragment instead of replacing it

ORIGINAL:
The setup I have is a main_activity fragment that just has welcome text, and when you tap the start button, it's supposed to switch fragments. Instead of replacing the current fragment, it just overlays it on top of the main_activity fragment and won't allow me to perform the action associated with the new fragment.
