public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
first_fragment.xml is like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"

FirstFragment class is like this
package fragments;
import com.example.testfragmentshoneycomb.R;
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FirstFragment extends Fragment{

super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.first_fragment, container, false);
return view;
}
}
It shows only first button and nothing else on the screen. If I remove the first button from activity_main.xml it shows the fragment but doesn't show the second button.
Min SDK version is 11 and build target is android 4.1
set android:orientation="vertical" in your activity layout.
Its because by default LinearLayout's orientation is horizontal. Therefore the whole screens width is captured by the First Button and Fragment.
Are you sure you want to see it like?
First_Button Fragment Second_Button
If Yes the use layout_weight. If No then give orientation=vertical to LinearLayout which will show your layout output as
First_Button
Fragment
Second_Button
set LinearLayout orientation to vertical, it's horizontal by default.
read docs carefully
Use the following layout :
<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" >
<Button
android:id="#+id/button_one_activity_one"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="First Button"
/>
<fragment
android:name="fragments.FirstFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/first_fragment" />
<Button
android:id="#+id/button_two_activity_one"

I have tried everything but still, I am not able to change Fragments from CalculatorP1 to Calculator_P2. When I click the button only one Fragment is shown but when I click the button again the second Fragment does not show itself in the APP. I tried everything and I also tried to use TWO BUTTONS bt only one Fragment Shows itself. The second Fragment doesn't show itself. If I switch the fragments only the first Fragment shows bt the 2nd fragment doesn't show itself.
Please help.
My App... See how the button text changes but the Fragment remains the same

I want to add 2 fragments in a single layout like this:
I was able to do it using static fragment method but not able to do it dynamically. I want to target API 14 and above.
Here is the code:

android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<FrameLayout
android:id="#+id/my_placeholder"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
</FrameLayout>
</LinearLayout>
fragment1.xml:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:layout_weight="1"
/>
</LinearLayout>
fragment2.xml:

android:layout_width="match_parent"
android:layout_height="match_parent"

setContentView(R.layout.activity_main);
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
// Create new fragment and transaction
Fragment newFragment = new fragment1();
Fragment myFragment = new fragment2();
FragmentTransaction transaction = getFragmentManager().beginTransaction();
// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack
transaction.add(R.id.new_placeholder, newFragment);
transaction.add(R.id.my_placeholder, myFragment);
transaction.commit();
}
}
In the output I am getting only first fragment displayed. The second fragment is not getting added. Output:
Can you please tell me what is going wrong?
please added android:layout_weight="1"
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal">

android:layout_width="match_parent"
android:layout_weight="1"
android:layout_height="match_parent">

android:layout_width="match_parent"
android:layout_weight="1"

You need layout weight android:layout_weight for both your frame layout
try below XML changes
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="2"
android:orientation="horizontal">
<FrameLayout
android:id="#+id/new_placeholder"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent">
</FrameLayout>
<FrameLayout
android:id="#+id/my_placeholder"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent">
</FrameLayout>
</LinearLayout>
The problem is in your activity_main.xml.
Use android:layout_weight="1" for each of your fragments container to show both of them on the screen.
Also fill_parent is deprecated. Consider using match_parent instead
First post. I'm following a few courses on Android programming so fairly new but not a complete newbie. I have a background in programming from long ago..
For some odd reason, older projects have the OnClick running fine but every project I created today, with either Genymotion or AVD the OnClick never fires even in the following barebone example I created.
https://www.dropbox.com/s/js1qh263vldte0z/deleteme.zip?dl=0
Here's the original project I'm working on which I can't even click on the buttons (as if there's a transparency in front or something).
If someone can explain why when I open older projects based on 22 everything works but running now on 23 (with 16 as backward) OnClick doesn't work that'd be very nice of you. Thanks!

This is the layout as seen by the user...
Try to add .setOnClickListener(this); inside onCreate(...) method.

Hope this help

public class MainActivity extends Activity implements MyListFragment.OnItemSelectedListener{

// if the wizard generated an onCreateOptionsMenu you can delete
// it, not needed for this tutorial
