In example mention below on click of a button, we attach the desired fragment in our frame layout which was present in activity_main.xml.
Step 1: -Open your project and design layout of your app in activity-main.xml.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/number_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.hp.myframepart2.MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:id="@+id/fragment_one"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/fragment_one"
android:onClick="sendframe"/>
<Button
android:id="@+id/fragment_two"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="@string/fragment_two"
android:onClick="sendframe"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="@+id/color_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
</LinearLayout>
</LinearLayout>
Step 2: -Create a new xml which act as the fragment which attaches to our frame layout.
fragment_one.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">
<TextView
android:id="@+id/fragment_field"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textSize="@dimen/textsize"
android:padding="@dimen/textpadding"
android:gravity="center"
android:textColor="@android:color/white"/>
</LinearLayout>
string.xml
<resources>
<string name="app_name">MyFramepart2</string>
<string name="fragment_one">FRAGMENT ONE</string>
<string name="fragment_two">FRAGMENT TWO</string>
</resources>
Step 3: -Create another java class to attach our fragment to frame layout.
TextFragment.java
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
public class TextFragment extends Fragment {
private View view;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
view=inflater.inflate(R.layout.fragment_one,container,false);
return view;
}
@Override
public void onStart() {
super.onStart();
Bundle bundle=getArguments();
if(bundle!=null){
String data=bundle.getString(MainActivity.TEXT);
int color=bundle.getInt(MainActivity.COLOR);
TextView textView=(TextView)view.findViewById(R.id.fragment_field);
textView.setText(data);
textView.setBackgroundColor(color);
}
}
}
Step 4: - To give text size or dimension we give it dynamically in dimen.xml.In it, we mention size or dimension and call it dynamically in a project. To create dimen.xml go to res→values(right click)→Values resource file then press ok.Inside dimen.xml you mention your dimension related requirement.
dimen.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<dimen name="textsize">25sp</dimen>
<dimen name="textpadding">16dp</dimen>
</resources>
Step 5: -Open your MainActivity.java class and type the code mention below to perform the operation.
MainActivity.java
package com.example.hp.myframepart2;
import android.graphics.Color;
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 {
public final static String TEXT = "org.mz.Activity.text";
public final static String COLOR = "org.mz.Activity.color";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void sendframe(View view) {
TextFragment changeFragmentOnClick = new TextFragment();
Button button = (Button) view;
Bundle bundle = new Bundle();
String buttonText = button.getText().toString();
if (buttonText.equals("FRAGMENT ONE")) {
bundle.putInt(COLOR, (Color.RED));
} else {
bundle.putInt(COLOR, (Color.BLUE));
}
bundle.putString(TEXT, buttonText);
changeFragmentOnClick.setArguments(bundle);
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.color_fragment, changeFragmentOnClick);
transaction.commit();
}
}
