Adding Dynamic Views in Linear Layout

How to add dynamic views in a parent view (Can be linear or relative etc.)


Here are the steps :


1. MainActivity.java

public class MainActivity extends ActionBarActivity {


LinearLayout mDynamicLinearLayout;
LayoutInflater __inflater;
Button mAddRow;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initiViews();
}

private void initiViews() {
mDynamicLinearLayout=(LinearLayout)findViewById(R.id.mDynamicLinearLayout);
mAddRow=(Button)findViewById(R.id.mAddRow);
mAddRow.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
addDynamicViews();
}
});
}

private void addDynamicViews() {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View _itemRow = inflater.inflate(R.layout.dynamic_row, null);
final EditText name=(EditText)_itemRow.findViewById(R.id.name);
final EditText password=(EditText)_itemRow.findViewById(R.id.password);
Button mShow=(Button)_itemRow.findViewById(R.id.mShow);
mShow.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, name.getText().toString()+ "pwd "+password.getText().toString(), Toast.LENGTH_LONG).show();
}
});
mDynamicLinearLayout.addView(_itemRow);
}

}

XML layouts goes here : 

1. activity_main.xml 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical" >

    <Button

        android:id="@+id/mAddRow"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:text="Add" />

    <ScrollView

        android:layout_width="match_parent"

        android:layout_height="match_parent" >

        <LinearLayout

            android:id="@+id/mDynamicLinearLayout"

            android:layout_width="fill_parent"

            android:layout_height="wrap_content"

            android:orientation="vertical" >

        </LinearLayout>

    </ScrollView>

</LinearLayout>

2. dynamic_row.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical" >

    <EditText

        android:id="@+id/name"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:layout_margin="10dp"

        android:hint="username" />

    <EditText

        android:id="@+id/password"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:layout_margin="10dp"

        android:hint="password" />

    <Button

        android:id="@+id/mShow"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:text="Show Values" />

</LinearLayout>

Output :
