将过滤器添加到具有两个textview的listview

Question

I have a custom ListView with two TexView , I fill it with a SimpleAdapter with this code below

adapter = new SimpleAdapter(this, list,
            R.layout.activity_lista_vehiculo,
            new String[] { "value1","value2" },
            new int[] {R.id.line_a, R.id.line_b});      
    setListAdapter( adapter );

How can i put a filter to it from an EditText or SearchView ?

SimpleAdapter has a build-in SimpleFilter which filters the content of your ListView adapter with a prefix. If this is what you want, you can use the following code to do the filter work:

            yourEditText.addTextChangedListener(new TextWatcher() {

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

                }

                @Override
                public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                        int arg3) {

                }

                @Override
                public void afterTextChanged(Editable arg0) {

                }
            });
