I want to make my layout for my first tab something like this:
I have already asked a question similar to this. I am getting stuck on the formatting:
This is what my code looks like:
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp">
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp" />
<RelativeLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/simpleMode"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding = "5dip"
android:layout_alignParentLeft="true"
android:src="#drawable/ic_tab_artists_grey" />
<TextView
android:id="#+id/right_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dip"
android:layout_toRightOf="#+id/simpleMode"
android:gravity="right"
android:text="Description" />
</RelativeLayout>
</LinearLayout>
</TabHost>
My project runs but absolutely nothing shows up on the screen? Help is very much appreciated!!
Here is my activity class:
package com.joshi.remotedoc;
import android.app.TabActivity;
import android.os.Bundle;
import android.widget.TabHost;
import android.content.Intent;
import android.content.res.Resources;
public class Detailed_ModeActivity extends TabActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.patientmode);
Resources res = getResources();
// Resource object to get Drawables
TabHost tabHost = getTabHost();
// The activity TabHost
TabHost.TabSpec spec;
// Reusable TabSpec for each tab
Intent intent;
// Reusable Intent for each tab
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, SimpleMode.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("simpleMode").setIndicator("simpleMode",
res.getDrawable(R.drawable.ic_tab_artists_white))
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, DetailedMode.class);
spec = tabHost.newTabSpec("2ndtab").setIndicator("MySecondTab", res.getDrawable(R.drawable.something)) .setContent(intent);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("detailedMode").setIndicator("detailedMode",
res.getDrawable(R.drawable.ic_tab_artists_grey))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(2);
}
}
You need to properly define your layout, then you need to load your layout in the activity you are starting.
http://developer.android.com/guide/topics/ui/declaring-layout.html
First you create your XML
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello, I am a TextView" />
<Button android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello, I am a Button" />
</LinearLayout>
Then you need to create the Java to load your XML in the oncreate method:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
}

I want to display the tab bar and listview but when my main activity launched then my tab bar gets hided... so tell me what is the problem in my xml or my src file.

it's because you declare the height of the content to fill the parent here
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
that's why the tabs is being overlapped by the content, what you need is android:layout_weight, so you need to change it to this
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" />
android:layout_weight will fill all the remaining space of the parent view so it won't overlap with each other

Where I am wrong? I am beginner in Android. Please Explain in Details if found solution.
I wrote above code by finding steps and solution on internet, but I am stucked here from past 4 days.
Please Help me.
This class was deprecated in API level 13. It is recommended to use Fragment and FragmentManager. If you not planning to use Fragment and FragmentManager APIs then you need to live with this warning message.
Please understand that this is a warning message only and not an error message. So you can still live with this. But recommended option is to use Fragment and FragmentManager APIs
You can see more details about the deprecated class here http://developer.android.com/reference/android/app/LocalActivityManager.html
Fragment - http://developer.android.com/reference/android/app/Fragment.html
FragmentManager - http://developer.android.com/reference/android/app/FragmentManager.html

thanks for the help!!!
if you use Tabhost then must have android:id="#android:id/tabhost" and You have
android:id="#+id/tabhost"
I am developing an Android application in which I have a tab bar. I want that when I click on tab new class should open. How do I implement this? My main problem is when I pass the intent on clicking the tab. Then it's crashing.
I am posting my Java:
package com.solataire;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;

/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TabHost tab_host = (TabHost) findViewById(R.id.tab_host);
tab_host.setup();
TabSpec tabspec1 = tab_host.newTabSpec("TAB_1");
tabspec1.setIndicator("Tab 1");
tabspec1.setContent(R.id.first_tab);
tab_host.addTab(tabspec1);
TabSpec tabspec2 = tab_host.newTabSpec("TAB_2");
tabspec2.setIndicator("Tab 2");
tabspec2.setContent(R.id.second_tab);
tab_host.addTab(tabspec2);
TabSpec tabspec3 = tab_host.newTabSpec("TAB_3");
tabspec3.setIndicator("Tab 3");
tabspec3.setContent(R.id.third_tab);
tab_host.addTab(tabspec3);
tab_host.setCurrentTab(0);
}
}

Can anyone help me in this point?
You can try this.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources(); // Resource object to get Drawables
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, ArtistsActivity.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("artists").setIndicator("Artists",
res.getDrawable(R.drawable.ic_tab_artists))
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, AlbumsActivity.class);
spec = tabHost.newTabSpec("albums").setIndicator("Albums",
res.getDrawable(R.drawable.ic_tab_albums))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, SongsActivity.class);
spec = tabHost.newTabSpec("songs").setIndicator("Songs",
res.getDrawable(R.drawable.ic_tab_songs))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(2);
}
This is the xml:
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"

I created xml layout for each tab this is one with the button
others are exactly this same just with out a button tag and with different id
tab2.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/tab2Layout"
android:orientation="vertical">
<Button android:text="#+id/Button01"
android:id="#+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</Button>
</LinearLayout>
and i created class for each tab this is code from second tab where i want to have a button
the other classes are exactly this same just
setContentView(R.layout.tab2);
is set to point to different layouts
SecondTab.java
public class SecondTab extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab2);
}
}
Any ideas ??
Thanks
solved it!!!
in main.xml i included those 4 lines:
<include layout="#layout/tab1"/>
<include layout="#layout/tab2"/>
<include layout="#layout/tab3"/>
<include layout="#layout/tab4"/>
those lines shouldn't be there
so main.xml looks like that now:
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp">
<FrameLayout android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dp">
</FrameLayout>
<TabWidget android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="bottom"/>
</LinearLayout>
</TabHost>
