使用SimpleCursorAdapter.ViewBinder更改Listview中的文本颜色

Question

I've listed the names from database using SimpleCursorAdapter and I want to change the color of a particular name using SimpleCursorAdapter.ViewBinder 's method. I've a problem while running this method, my database contains different names but the ListView will display all the namse as one particular name. What am I doing wrong? How to change the text color of a specific name? Is it possible using ViewBinder ?

This is my part of of code for ViewBinder :

    SimpleCursorAdapter.ViewBinder binder = new SimpleCursorAdapter.ViewBinder() {

    @Override
    public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
        // TODO Auto-generated method stub
        String[] temp = dh.return_result();
        tv = (TextView)findViewById(R.id.textView1);
        tv = (TextView) view;
        for(int i = 0; i<temp.length; i++)
        {
            if(temp[i].equalsIgnoreCase("Ameer Zhann"))
            {
                tv.setText(temp[i]);
                tv.setTextColor(Color.rgb(58, 58, 224));
                return true;
            }
        }
        return false;
    }
};

and this is my output image:

How can I solve this?

Answer 1

Try this way:

public boolean setViewValue(View view, Cursor cursor, int columnIndex){    
    int getIndex = cursor.getColumnIndex("Name");
    String empname = cursor.getString(getIndex);
    tv = (TextView) view;
    tv.setTextColor(Color.WHITE);
    tv.setText(empname);
    if(empname.equals("Any String"))
    {                   
        tv.setTextColor(Color.rgb(58, 58, 224));
        return true;
    }
    return false;           
}

Answer 2

Code do exactly what you ask - for every element in Cursor you go through all list and set text of each element. I think that "Ameer Zhann" is last result in your list, so only this text left in TextView .

Method setViewValue(...) called for every element of Cursor . So, you don't need any cycle, just fill text with cursor value tv.setText(Cursor.getString(...)); .

Also there is something strange with this code:

tv = (TextView)findViewById(R.id.textView1);
tv = (TextView) view; 

view that comes as param - is already view with id R.id.textView1 - so just remove call of findViewById .

Answer 3

try with the else part

if(temp[i].equalsIgnoreCase("Ameer Zhann")){
    tv.setText(temp[i]);
    tv.setTextColor(Color.rgb(58, 58, 224));
}else{
    tv.setText(temp[i]);
}

and at the end return true instead of false
