I am trying to create a LinearLayout with TextViews in Java, because the number of elements is dynamically specified so using XML won't work out for me. Here is a little sample of my Code:
public class MyActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); LinearLayout layout = new LinearLayout(this); layout.setOrientation(LinearLayout.VERTICAL); layout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); TextView titleView = new TextView(this); titleView.setWidth(LayoutParams.WRAP_CONTENT); titleView.setHeight(LayoutParams.WRAP_CONTENT); titleView.setTextAppearance(this, android.R.attr.textAppearanceLarge); titleView.setText("Hallo Welt!"); layout.addView(titleView); setContentView(layout); } }
When i start this activity it does not show this TextView but it also does not show an error. Does anyone have an advice?
