As Android developer you will surely need someday to add views dynamically, instead of creating a ListView. I will show you in this tutorial how to do this 🙂
1. Create a new project and call your activity “MyActivity”
2. Go to res – layout – main.xml and put the following code:
|
1 2 3 4 5 6 7 8 9 10 11 |
<?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/scroll"> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/layout" android:orientation="vertical"/> </ScrollView> |
3. Go to res – layout and create a new xml called text_layout.xml and put the following code:
|
1 2 3 4 5 6 |
<?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/text"/> |
4. Now go to MyActivity class and put the following code:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 |
package com.example; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.widget.LinearLayout; import android.widget.ScrollView; import android.widget.TextView; public class MyActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Parent layout LinearLayout parentLayout = (LinearLayout)findViewById(R.id.layout); // Layout inflater LayoutInflater layoutInflater = getLayoutInflater(); View view; for (int i = 1; i < 101; i++){ // Add the text layout to the parent layout view = layoutInflater.inflate(R.layout.text_layout, parentLayout, false); // In order to get the view we have to use the new view with text_layout in it TextView textView = (TextView)view.findViewById(R.id.text); textView.setText("Row " + i); // Add the text view to the parent layout parentLayout.addView(textView); } } } |
And now you should have a list with 100 rows that can be scrolled.
