Question

I want to achieve this functionality: dynamically add multiple button to the scrollview, if scrollview more than a certain height, it is will automatically diplay scroll bar.

can you give me some advice?

Answer 1

check the following code snippet:

// Find the ScrollView 
ScrollView scrollView = (ScrollView) findViewById(R.id.scrollView1);

// Create a LinearLayout element
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);

// Add Buttons
Button button = new Button(this);
button.setText("Some text");
linearLayout.addView(button);

// Add the LinearLayout element to the ScrollView
scrollView.addView(linearLayout);
