如何在文本索引的特定索引处设置字符串

Question

How to set string at a particular index to a textview. The below code is not working for me.

TextView t1 = (TextView) findViewById(R.id.textView1);
String[] picname ={"abc","def"};
String data=picname[0];
t1.setText(data);

Answer 1

Try this:

int position = 1; // Position on EditText
Editable etext = t1.getText(); // getText() Optional
Selection.setSelection(etext, position);

Answer 2

Use this one

 String name = "data number"  

String[] firstname = name.split(" "); 
String first_Name = firstname[0];
String last_Name = firstname[1];    

Answer 3

Try updating the text on the ui thread.

private void updateText()
{
   runOnUiThread(new Runnable() 
   {
        public void run() 
        {
              TextView t1 = (TextView) findViewById(R.id.textView1);
              String[] picname ={"abc","def"};
              String data=picname[0];
              t1.setText(data);
        }
   });     
}
