Android::findViewByID - how can I get View of a TextView through a Listener of another UI element?

This is going to be a bit lame question. I have the following code:

..............
 public void onCreate (Bundle bundle)
 {
  super.onCreate(bundle);
  this.setContentView(R.layout.main2);
  Button bnt = (Button) this.findViewById(R.id.browser);
  bnt.setOnClickListener(new ButtonListener());

 }
..............
class ButtonListener implements android.view.View.OnClickListener
{

 public void onClick开发者_高级运维(View v) 
 {
  // I have a TextView in my xml layout file. 
  // I'd like to get it and change my text when I click this button.
  // But I can't get it (the TextView) unless I make it as a value of a static member of this class and pass it to the constructor. 
  //I believe I am missing a big point here, so i'd be very thankful if you could explain how this is meant to be done ? 

 }
}

Any help is appreciated.

You could try this:

class ButtonListener implements android.view.View.OnClickListener {
    public void onClick(View v) {
        View parent = (View)v.getParent();
        if (parent != null) {
            TextView txtView = parent.findViewById(R.id.mytextview);
            txtView.setText(...);
        }
    }
}

the usage depends on your layout. Its possible, that the parent of your button is not the parent of your textview so be careful...

class ButtonListener implements android.view.View.OnClickListener {
    public void onClick(View v) {
       View p = (View) view.getRootView();        
        if (p != null) {
            TextView txtView = (TextView) p.findViewById(R.id.mytextview);
            txtView.setText(...);
        }
    }
}

I need to set visible an element from the same parent so I used this code :) and it worked

EDIT I dont think it will be possible. The view V only has the buttons view in it....

You will know if you typecast the same

  class ButtonListener implements android.view.View.OnClickListener
    {

     public void onClick(View v) 
     {

        Button vg=(Button)v;
        Log.e("", "views are "+vg.getText());

//However u can set the test here for ue textview txt.setText("change text");

     }
    }

I did not understand your question properly. But if you just want to get the text out from ur TextView you can try like this

TextView txt;

public void onCreate (Bundle bundle)
 {
  super.onCreate(bundle);
  this.setContentView(R.layout.main2);
  Button bnt = (Button) this.findViewById(R.id.browser);
  txt=(TextView)this.findViewById(R.id.urtextview);
  bnt.setOnClickListener(new ButtonListener());

 }
..............
class ButtonListener implements android.view.View.OnClickListener
{

 public void onClick(View v) 
 {
  // I have a TextView in my xml layout file. 
  // I'd like to get it and change my text when I click this button.
  // But I can't get it (the TextView) unless I make it as a value of a static member of this class and pass it to the constructor. 
  //I believe I am missing a big point here, so i'd be very thankful if you could explain how this is meant to be done ? 
//I think this should get u the string...
System.out.println("text is "+txt.getText().toString());

 }
}
