Dynamically Display String text on Android Screen
I have an array of classes that contain two strings for开发者_高级运维 each class. I'm trying to display these two strings (they're sentences) on the screen when a button is clicked at two different locations (middle of the screen, and the other sentence right above that).
The problem is that I only know how to get text on the screen through the XML layout file, not dynamically. How would I go about doing this? I already have the buttons and background done in XML.
Thanks!
To add a view dynamically. Use the addView function.
public MyActivity extends Activity {
private TextView myText = null;
@Override
public onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.id.mylayout);
LinearLayout lView = (LinearLayout)findViewById(R.id.mylinearlayout);
myText = new TextView();
myText.setText("My Text");
lView.addView(myText);
}
If you don't want to use an xml file at all:
//This is in the onCreate method
LinearLayout lView = new LinearLayout(this);
myText = new TextView(this);
myText.setText("My Text");
lView.addView(myText);
setContentView(lView);
It's not totally clear how you want to display the text, BUT you most certainly could use a Toast message:
Toast.makeText(getApplicationContext(), "Sample Text", Toast.LENGTH_LONG).show();
