Pass a Message From Thread to Update UI

Question

Ive created a new thread for a file browser. The thread reads the contents of a directory. What I want to do is update the UI thread to draw a graphical representation of the fi

Answer 1

It seems passing simple messages is int based... What I needed to do was pass a Bundle

using Message.setData(Bundle) and Message.getData(Bundle)

So Happy =0)

//Function From Within The Thread

public void newProjectCreation() {

Message msg =  new Message();
Bundle bundle = new Bundle();

bundle.putString("Test", "test value");
msg.setData(bundle);

handler2.sendMessage(msg);
}

//Handler in The UI Thread Retreieves The Data
//And Can Update the GUI as Required

private Handler handler2 = new Handler() {
    @Override
    public void handleMessage(Message msg) {

    Bundle bundle = msg.getData();
    Toast.makeText(New_Project.this,bundle.getString("Test"),Toast.LENGTH_SHORT).show();

}

};
