Try the below

EditText inputSearch; 
ArrayAdapter adapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
inputSearch = (EditText) findViewById(R.id.inputSearch); // initialize edittext 
list1 = (ListView) findViewById(R.id.ListView01);
adapter =new ArrayAdapter(this,android.R.layout.simple_list_item_1, array));
list1.setAdapter(adapter);
inputSearch.addTextChangedListener(new TextWatcher() {

@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
    // When user changed the Text
    MainActivity.this.adapter.getFilter().filter(cs);   
}

@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
        int arg3) {
    // TODO Auto-generated method stub

}

 @Override
public void afterTextChanged(Editable arg0) {
    // TODO Auto-generated method stub                          
}
});
list1.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View view,
        int position, long id) {
     if (position == 1)
    {
      Intent myIntent = new Intent(getApplicationContext(),Baba.class);
      startActivity(myIntent);
    }
  }
});
}

Initialize editText inputSearch in onCreate.

inputSearch = (EditText) findViewById(R.id.inputSearch); // initialize edittext 

Initialize adapter

adapter =new ArrayAdapter(this,android.R.layout.simple_list_item_1, array));

Set the adapter op listview

list1.setAdapter(adapter);

This is where the search happens

 @Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
    // When user changed the Text
    MainActivity.this.adapter.getFilter().filter(cs);   // filter based on input
}
