remove android:onClick="onClick" line. That should be work.

How to store images in SQLite and also how I can export input text and image in any tabular format?

1) Please help me out to store image submitted by button to SQLite.
2) How can I implement export function in my app so that all the input text and images stored in SQLite can be exported in any format but in tabular way so that exported file can be used to retrieve data again.

The answer to your question is lengthy - and will require you to make many changes.
Saving Images:
If you want to save the images, you will need to convert the image to a byte array
A more feasible approach, is to save the image as a File within your app's internal storage, add a column to your database which saves the name of the image in a common directory "s8u903wmips.jpg" as an example.
Exporting Data:
Content Providers are created for exactly this reason. https://developer.android.com/guide/topics/providers/content-providers.html
Content providers are one of the primary building blocks of Android applications, providing content to applications. They encapsulate data and provide it to applications through the single ContentResolver interface. A content provider is only required if you need to share data between multiple applications. For example, the contacts data is used by multiple applications and must be stored in a content provider. If you don't need to share data amongst multiple applications you can use a database directly via SQLiteDatabase.

Please someone give me simple example or other help :)

Create this method:-
private static View createTabView(Context context, String tabText) {
View view = LayoutInflater.from(context).inflate(R.layout.custom_tab, null, false);
TextView tv = (TextView) view.findViewById(R.id.tabTitleText);
tv.setText(tabText);
return view;
}
Create custom_tab.xml file in layout folder
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tabTitleText"
android:layout_width="#dimen/tabWidth"

android:paddingLeft="#dimen/tabLeftPading"
android:paddingRight="#dimen/tabRightPading"
android:textSize="#dimen/tabTextSize"
android:textColor="#color/themeColor"
android:background="#drawable/tab_selector"/>
finally set
tabHost.newTabSpec("Tab1").setIndicator(createTabView(getApplicationContext(),"Tab_name"))

AdapterViewFlipper would be the best way to go since, in a ViewFlipper you need to pre define the views.
Inside onCreate :
ArrayList<String> urls;
//Fetch and set urls to this ArrayList;
AdapterViewFlipper flipper = (AdapterViewFlipper) findViewById(R.id.flipper);
flipper.setAdapter(new FlipperAdapter(urls));
FlipperAdapter.java
For loading image from urls, I'd suggest the use of the Universal Image Loader library : https://github.com/nostra13/Android-Universal-Image-Loader
public class FlipperAdapter extends BaseAdapter {
ArrayList<String> urls;
public FlipperAdapter(ArrayList<String> urls) {
this.urls = urls;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return urls.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return urls.get(position);
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = (LinearLayout) LayoutInflater.inflate(
R.layout.viewLayout, parent, false);
}
ImageView image = (ImageView) convertView.findViewById(R.id.image);
imageLoader.displayImage(urls.get(position), image, null);
return convertView;
}
}
Edit 1 : viewLayout.xml (This will contain the layout of the items you want to display inside the adapterViewFlipper)
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>

How to View data, based on date input(edittext)?

I wanted to do a view output using table layout.
My idea goes like this.
I have a main page, known as activity_main.xml
when you click on the cancel button, it will go to a summary page,
know as data.xml.
In data.xml, I have a date edittext, whereby ,when I enter a date,eg 12/2/2013,
and after I click the button search, it will show me the record of it.
However, I'm not sure how to do it.
If I didn't enter any date and click "search", it will show all the records.
Right now,I am able to show all the records, without searching the data.
Below is my code.
Can someone kindly help me out with the search by date?
I hope that I've explained myself clear enough.

The error you are getting is a nullpointer that means that some object that is at line 205 in MainActivity or it is used at that line is null. Check that first and then try to run again.

The immediate problem is here:
catch (Exception e)
{
Log.d("Fuel Log", e.getMessage());
}
Not all throwables have a message and a null can be returned. A null cannot be logged. It causes the "println needs a message" exception in the stacktrace.
So first, change that to e.g.
catch (Exception e)
{
Log.e("Fuel Log", "", e);
}
This will log the exception with error level, empty message and with full stacktrace.
Then you can see what causes that exception in the first place.

Hello date type is not supported in Sqlite Database.you have assign date as text so it will take string so you need to keep string in proper order so that it can work as date search.
You can store date in form of 2013-12-23 (20131223) then you can get your query by passing date
by the way you can try like below
public ArrayList<String> getEventsForNotification(String dateSearch)
{
ArrayList<String> arrayList=new ArrayList<String>();
String sql="SELECT "+KEY_EVENT_NAME+" FROM "+ TABLE_EVENT +" WHERE SUBSTR("+KEY_EVENT_DATE+",6) like '"+dateSearch+"'";
Cursor cursor=sqLiteDatabase.rawQuery(sql, null);
if(cursor.moveToFirst())
{
do
{
arrayList.add(cursor.getString(0));
}while(cursor.moveToNext());
cursor.close();
cursor=null;
}
return arrayList;
}
modify according to your need.
