Question

In my application I have a TextView, when the user clicks for thr first time on it I have to arrange the data in descending order,When user click on the same text view once again I have to arrange the data in ascending order.Is there any way to accomplish this?

My Code:

public void onClick(View v) {
    // TODO Auto-generated method stub
    boolean flag = false;
    db.open();
    Cursor c;
    if(flag==false)
    {
        c = db.getIncomeTitleDescitem(intent.getStringExtra("grpsdb"));
        startManagingCursor(c);
        flag=true;
    }                   
    else
    {
        System.out.println("inside else");
        c = db.getIncomeTitleAscitem(intent.getStringExtra("grpsdb"));
        startManagingCursor(c);
        flag=false;
    }
    ListView lv=(ListView)findViewById(R.id.listView1);     
    String[] fromdes = new String[] {db.KEY_DATE,db.KEY_DESC,db.KEY_INCOME,db.KEY_TOTAL};
    int[] todes = new int[] {R.id.text1 ,R.id.text3,R.id.text5,R.id.text7};
    SimpleCursorAdapter notes = new SimpleCursorAdapter(IncomeDetails.this, R.layout.columnview, c, fromdes, todes);                          
    lv.setAdapter(notes);  
    db.close();             
}

Yes you can easily track with a flag, based on click update the flag.. flag you can keep as boolean or int whatever you want. For your reference…

boolean flag = false;   // false - first click, true - second click
textView.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        if (flag == false) {
            flag = true;
            // do descending
         } else {
             flag = false;
             // do ascending
         }                
    }
});
