I am trying to set the ActionBar to a tab activity in android. i tried a lot.
But can't solve this topic. i'm using the Tab Activity, i want to display actionbar above the tabhost. How can I add actionbar in this activity?
I'm using the android studio and sdk is 25
here is my code:
package com.example.lenovo.monitoringapp;
import android.app.TabActivity;
import android.content.DialogInterface;
import android.content.Intent;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ArrayAdapter;
import android.widget.TabHost;
import android.widget.TabWidget;
import android.widget.Toast;
import android.widget.TabHost.TabSpec;
public class KwhActivity extends TabActivity {
TabHost TabHostWindow;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_kwh);
TabHostWindow = (TabHost) findViewById(android.R.id.tabhost);
TabSpec TabMenu1 = TabHostWindow.newTabSpec("Graph");
TabSpec TabMenu2 = TabHostWindow.newTabSpec("Data List");
TabMenu1.setIndicator("Graph");
Intent intent = new Intent(KwhActivity.this, GraphActivity.class);
// intent.putExtra("uname", username);
// Set tab 1 activity to tab 1 menu.
TabMenu1.setContent(intent);
// Setting up tab 2 name.
TabMenu2.setIndicator("Data List");
Intent i1 = new Intent(KwhActivity.this, DataListActivity.class);
// i1.putExtra("uname", username);
// Set tab 3 activity to tab 1 menu.
TabMenu2.setContent(i1);
TabHostWindow.addTab(TabMenu1);
TabHostWindow.addTab(TabMenu2);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.kwhactivity, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_other1:
AlertDialog.Builder builderSingle = new AlertDialog.Builder(KwhActivity.this);
builderSingle.setIcon(R.drawable.calender);
builderSingle.setTitle("Select");
final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(KwhActivity.this, android.R.layout.select_dialog_item);
arrayAdapter.add("Today");
arrayAdapter.add("Yesterday");
arrayAdapter.add("Week");
arrayAdapter.add("30 Days");
arrayAdapter.add("Year");
builderSingle.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
builderSingle.setAdapter(arrayAdapter, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
String strName = arrayAdapter.getItem(which);
if(strName == "Today")
{
Toast.makeText(KwhActivity.this, "Today!",
Toast.LENGTH_LONG).show();
}
}
});
builderSingle.show();
break;
default:
break;
}
return false;
}
}
Here is activity_main.xml file
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffffff">
<TabHost
android:id="#android:id/tabhost"
android:layout_width="match_parent"

android:background="#drawable/rounded_edittext"
android:layout_marginTop="10dp"
android:layout_marginEnd="10dp"

<FrameLayout

Use Toolbar above TabHost by using below code;
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />

Text Visible in other Activities,

i just needed some quick help. I got a nav drawer setup, and i use activity main as my welcome screen, so I put a text box on the activity_main, but the problem is that when I chose other nav drawer pages, i see the text box from the activity main.
What one of my activity pages should look like: http://puu.sh/nQFkc/1ed83811cc.png
What it ends up looking like: http://puu.sh/nQF93/785c9eee45.png
Need to mention im new to android?

The issue is with your layout.
Two approaches to fix your problem -
Whenever you instantiate any fragment by selecting any option from the navigation drawer, you can set ScrollView (containing the welcome text) visibility to GONE.
Scrollview scrollView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
scrollView = (ScrollView) findViewById(R.id.scrollView);
}
private void selectItem(int position) {
scrollView.setVisibility(View.GONE);
....
}
Create a one more fragment with the layout where you only show your welcome text and launch this fragment in onCreate() of your activity. So this will show the welcome text when user starts your app. and when user selects any item from Navdrawer, you can launch another fragment of your choice. But for this you should remove welcome text from activity layout xml.

Locate fragment (android)

I have created ViewPager and tabs. But unfortunately the fragments have added not below the titel of the tabs. I want that the fragment (LoginFragment and ProfleFragment) were located below titles of tabs (Login). How can I do it? Now they look this way (disgusting view):
It's not possible to see textview "username" and texfield for username
How can I cange xml laoyout or add code to locate them correctly?
Here is my code:
profilefragment.xml:
<?xml version="1.0" encoding="utf-8"?>

Android Fragments showing irregular behavior

I have multiple fragments in my Activity. It should initiate only first fragment at start up. It initializes the second one also. More over I move from one fragment to the other though a swipe action. When I swipe from first fragment to the next, third in the row is also initiated.
I have to get data from the server and then populate that fragment. Network request is sent but not for the one for which I am sending but for the fragment next to it.
Please suggest me where I am mistaken...
Thanks in advance.
Following is the code:
Note: Sample code is being used, Please consider the other fragments and their layouts as the same as that for Fragment1.

I achieved it by placing the following code at the end of OnPageChangeListener.onPageSelected()
Fragment fragment = _adapter.getFragment(previousFragment);
if(fragment != null) {
fragment.onPause();
}
I am using onPause() in the following way
public void onPause(){
super.onPause();
onDestroyView();
}
public void onDestroyView() {
super.onDestroyView();
onDestroy();
}
public void onDestroy() {
super.onDestroy();
onDetach();
}
public void onDetach() {
super.onDetach();
}

this is a known issue, that ViewPager(FragmentAdapter(Fragements)) created and destroyed according to the actual page.
I also came across with this situation, furthermore the data (Object) not referenced, because of a destroy will be collected by the GC so this is difficult.
I would use a static object at the main Activity and with the onRetainNonConfigurationInstance method I would save and load Fragment state.
Also found another solution which concentrated on the passed data between the Fragments (A,B and passed String data) here.
I hope one of these solutions are suitable for you!

Just call setOffscreenPageLimit() in onCreate() (after initializing ViewPager). The OffscreenPageLimit sets the number of pages that should be retained to either side of the current page. Set the minimum number of fragments you want to initiate either side.

Button duplication in android when setting new text

I am working with the android support library, to be able to use fragments from Froyo, and the Sherlock extension, to show an ActionBar.
I have a fragment which shows three textViews and a button, and I want to be able to change the button text dinamically, depending on the content of the Intent. The problem is that when I call button.setText(String text), a second button appears. However, I've called button.getId() when clicking on each of them, and the Id is the same. I don't have a clue of why this is happening, so I'd appreciate some help.
The app is run on a Samsung Galaxy S, with Android 2.3.3. I can't upload a screen capture because I don't have enough reputation yet :(
This is the code:

Thanks!

I think I might have found the problem. I was calling
b = (Button) getSherlockActivity().findViewById(R.id.button);
but it should be
b = (Button) getView().findViewById(R.id.button);
With that change it works correctly
