Question

Suppose my current activity is Main.java and I have already declared its layout through setContentView(R.layout.layout1) from its onCreate method. Now, is it in any way possible for me to access a different layout? For e.g., assuming there is another layout – layout2 which has TextView with id tv, then I won’t be able to execute the following code from Main.java :

TextView text = (TextView) findViewById(R.id.tv);
text.setText("blah blah");

Is there any way that I can set tv‘s value from Main.java.

My actual code is the following

setContentView(R.layout.layout);
Button button = (Button) findViewById(button);
    button(buttonListener);
Dialog dialog;

Inside the listener, I have the following code:

TextView dialogTitle = (TextView) findViewById(R.id.dialog_title);
        dialogTitle.setText("Email");

        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        View customView = getLayoutInflater().inflate(R.layout.dialog, null);
        builder.setView(customView);            

        dialog = builder.create();
                    dialog.show();

The problem that I am facing is that dialog_title is in dialog.xml and not in layout.xml

Answer 1

AlertDialog.Builder builder = new AlertDialog.Builder(this);
        View customView = getLayoutInflater().inflate(R.layout.dialog, null);
        builder.setView(customView);      
TextView dialogTitle = (TextView) customView.findViewById(R.id.dialog_title); 
dialogTitle.setText("Email");
