As a newbie, I have been reading posts in learning how to do different functions. Using the Hello World example, I added a textview object to this application but the results come back as false on the screen. Here's my code:
main.xml: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android";> <Button android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Click Me" android:layout_centerInParent="true"></Button> <TextView android:text="@+id/TextView01" android:id="@+id/TextView01" android:layout_below="@id/Button01" android:layout_height="wrap_content" android:layout_width="fill_parent"></TextView> </RelativeLayout> --------------------------------------------------------------------------------------------------------------------------------- Hello.java package com.HelloWorld; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.TextView; import android.widget.Toast; public class Hello extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // start code here TextView tv = new TextView(this); tv.setText("This is sample."); Button button = (Button) findViewById(R.id.Button01); button.setOnClickListener(new OnClickListener() { public void onClick(View v) { // TODO Auto-generated method stub Toast.makeText(Hello.this, "Hello World", Toast.LENGTH_SHORT).show(); } }); } } --------------------------------------------------------------------------------------------------------------------------------- Note that the example included a clickable button which has a popup to say "Hello World". That works just fine, but setting the text in the TextView comes out as false. Originally I wanted to click on the button and present the results in a TextView, but I was unable to do that unless someone can shed some light on that. Any suggestions on why I am getting the "false" reading and if anyone can suggest on how to place the results in a TextView via a button click, that would be appreciated. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
