xml layout loads but my activity doesn't respond to button clicks

I'm new at this but I already made a small app that worked the same way.
I can't see what I'm doing wrong because the code looks quiet the same as my previous app.
When I run it or debug my app it shows my layout on my emulator so it does load the page that has to be loaded but that's all it does, it doesn't listen to button clicks. I also gives me no errors.
Here's my XML code for fragment_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Thanks in advance!

Fixed it by making a new project with the same code, had to be a problem way deeper than my code.

Text is not getting entered in the edit text control

When I am trying to create tab control and add an edit text in Android, and then enter any character from UI (within Tab1 for Edit Text), the text is not getting entered in the edit text control. I am using Android Studio 1.1.0. Code is as follows.

Up caret shows navigation drawer

Nothing much more to say. I'm using a single activity and I go into a Fragment which calls setDisplayHomeAsUpEnabled(Boolean.TRUE) and setHasOptionsMenu(Boolean.TRUE). The menu has two items and the interactions with them are right. I have set breakpoints on all onOptionsItemSelected of the app (which includes the Activity, the Fragment, and the drawer toggle) but when I debug, the menu opens and no breakpoint is triggered.
The Activity and Fragment code in case they help:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

I have opted for making an activity only for that fragment which doesn't include the nav drawer. But obviously this doesn't answer the question, it just gets a relatively similar behavior.

how to remove the black line

I'm using android 2.3.3. I've created two tab indicators using custom layout, but there is always a black line between them. Below is the result screen.
I want to delete or hide the two black lines. I think those two are tab dividers, so I using
tabHost.getTabWidget().setDividerDrawable(null)
to delete divider, but nothing happens.
Below is my code:
package com.intasect.htfutures.activities;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageButton;
import android.widget.TabHost;

import android.widget.TabWidget;
import com.intasect.core.tab.TabMainActivity;
import com.intasect.htfutures.activities.competitionpk.PkActivityGroup;
import com.intasect.htfutures.activities.home.HomeActivityGroup;
import com.intasect.htfutures.utils.Const;
public class MainActivity extends TabMainActivity {
int currentTabId = 0;
public static TabHost tabHost;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tabHost = getTabHost();
final TabWidget tabwidges = tabHost.getTabWidget();
Intent intent;
// 首页
intent = new Intent(this, HomeActivityGroup.class);
tabHost.addTab(tabHost.newTabSpec(String.valueOf(TAB_ID_HOME))
.setIndicator(createView(TAB_ID_HOME, true)).setContent(intent));
// 业绩PK
intent = new Intent(this, PkActivityGroup.class);
tabHost.addTab(tabHost.newTabSpec(String.valueOf(TAB_ID_PK))
.setIndicator(createView(TAB_ID_PK)).setContent(intent));
// 设置
// intent = new Intent(this, SettingsActivityGroup.class);
// tabHost.addTab(tabHost.newTabSpec(String.valueOf(TAB_ID_SETTINGS))
// .setIndicator(createView(TAB_ID_SETTINGS)).setContent(intent));
/*
* 设置tab监听事件，改变背景颜色
*/
tabHost.setOnTabChangedListener(new OnTabChangeListener() {
#Override
public void onTabChanged(String tabId) {
currentTabId = tabHost.getCurrentTab();
chooseTab(tabwidges, currentTabId);
}
});
tabHost.setCurrentTab(currentTabId);
Const.initApp();
}
private static final int TAB_ID_HOME = 0;
private static final int TAB_ID_PK = 1;
// private static final int TAB_ID_SETTINGS = 2;
private static final int TOTAL_TAB_COUNT = 2;
private static final int[] IMAGE_IDS = { R.drawable.btn_tab_home,
R.drawable.btn_tab_home_selected, R.drawable.btn_tab_query,
R.drawable.btn_tab_query_selected };
private View createView(int tabId) {
return createView(tabId, false);
}
private View createView(int tabId, boolean choosed) {
ImageButton image = new ImageButton(this);
changeTabImage(image, tabId, choosed);
return image;
}
private void changeTabImage(ImageButton image, int tabId, boolean choosed) {
image.setImageResource(choosed ? IMAGE_IDS[tabId * 2 + 1]
: IMAGE_IDS[tabId * 2]);
image.setBackgroundColor(choosed ? Color.WHITE : getResources().getColor(R.color.tab_item_gray));
}
private void chooseTab(TabWidget tabwidges, int tabId) {
resetAllTabToUnselected(tabwidges);
ImageButton image = (ImageButton) tabwidges.getChildAt(tabId);
changeTabImage(image, tabId, true);
}
private void resetAllTabToUnselected(TabWidget tabwidges) {
for (int i = 0; i < TOTAL_TAB_COUNT; i++) {
ImageButton image = (ImageButton) tabwidges.getChildAt(i);
changeTabImage(image, i, false);
}
}
}
my layout 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"
android:layout_height="fill_parent"
android:background="#android:color/white" >
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingBottom="66dip" />
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_margin="0dp"
android:divider="#null"
android:fadingEdge="none"
android:fadingEdgeLength="0dp"
android:padding="0dp"
android:tabStripEnabled="false" />
</TabHost>
I've tried many ways to delete those two lines, but there is no miracle. How can I remove them?

i figured out by myself.i'm really sorry to ask such a stupid question.that black line is not divider,it is on my picture.i delete that line in my picture,every thing goes perfect.

add these lines in xml for Tabhost|TabWidget
android:divider="#null"
android:fadingEdge="none"
android:fadingEdgeLength="0dp"

When i go in inner fragments of tab1 , like from fragmentA -> Fragment B and From FragmentB -> fragmentC (and finally i am at fragmentC) , When i select Tab1 again i want to reload tabs and FragmentA should Apper.
Any help will be appreciated. I had gone through some of tutorials and coderepository but couldn`t found solution to my problem.
How Can i reload The content Of First tab when first tab is clicked again.

I had asked a question
When i go in inner fragments of tab1 , like from fragmentA -> Fragment B and From FragmentB -> fragmentC (and finally i am at fragmentC) , When i select Tab1 again i want to reload tabs and FragmentA should Apper.
I searched a lot and come to the conclusion , We can implement OnTabChangeListner and when any tab is clicked again we can reset it.(I was having need to reload tab when it is clicked 2nd time)

Code for BaseFragment is
extend this class with all sub fragment which you are going to add on (While adding fragment use myhomescreenActivity(This object) and call add Function in MyHomeScreen ):
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
public class BaseFragment extends Fragment {
protected MyHomeScreen myhomescreenActivity;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myhomescreenActivity = (MyHomeScreen) this.getActivity();
}
public boolean onBackPressed() {
return false;
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
}
}
This is the link of repository on Github for further understanding.......
https://github.com/thankimanish/TabUsingFragment

1.You can try moving your code inside the onCreate method to the onResume method so that every time fragment comes to front the code inside the onResume gets executed and reloads the frament.
2.You can also try overriding the onHiddenChanged method of the fragment and reload the fragment as soon as fragment becomes visible
