要在Simpleadapter上搜索过滤器的EditText吗？

Question

So I have a SimpleAdapter set up and I want to add an editText above it that you can enter your search query into and have the list update in real-time.

I know I can already setTextFilterEnabled(true) and force a keyboard popup. I was going to simply do that when you press an editText and just be done with it.

The problem I'm having is that the box that pops up with the letters when you search is really ugly and too big. It takes up literally 1/4 of the screen, covering your search results. Is there a way to customize this? Is there a way to use an editText for a simpleAdapter in this case so I can remove that box altogether?

You have to add the addTextChangedListener with a TextWatcher .

Boolean[] isPresent;

ed = (EditText) findViewById(R.id.editText1);
    ed.addTextChangedListener(new TextWatcher() {

            @Override
            public void afterTextChanged(Editable arg0) {
                // TODO Auto-generated method stub

            }

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

            }

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

                textLength = ed.getText().length();
                list.clear();
                isPresent = initIsPresentArray();

                for (int i = 0; i < tempList.length; i++) {
                    for (int j = 0; j < (tempList[i].length() - (textLength - 1)); j++) {
                        if (textLength <= tempList[i].length()) {
                            if (isPresent[i] == false) {
                                if (ed.getText()
                                        .toString()
                                        .equalsIgnoreCase(
                                                (String) tempList[i]
                                                        .subSequence(
                                                                j,
                                                                (j + textLength)))) {
                                    list.add(tempCaseList.get(i));
                                    isPresent[i] = true;
                                }
                            }
                        }
                    }
                    if (list.size() == 0) {
                        error.setText(getResources().getString(R.string.notFound));
                    } else {
                        error.setText("");
                    }

                    lv.setAdapter(new CustomAdapter(History.this, list));
                }
            }
        });

And the method initIsPresentArray()

 public Boolean[] initIsPresentArray() {
            Boolean[] isPresent = new Boolean[tempCaseList.size()];
            for (int i = 0; i < isPresent.length; i++) {
                isPresent[i] = false;
            }
            return isPresent;
        }

As you may see, I don't do operation directly on the ArrayList containing the information, but I copy this ArrayList over to a temporary ArrayList , using this method

public ArrayList<Case> createTempList(ArrayList<Case> listOfCases) {

    ArrayList<Case> temporaryList = new ArrayList<Case>();

    for (Case c : listOfCases) {
        temporaryList.add(c);
    }

    return temporaryList;
}

Just add a comment if something is uncleared!

Answer 2

While Tobias' answer was insightful, it did not answer my question and was fairly complex for what I needed to do. Rather than clearing and reloading the list each time, I opted to using a Filter in the array adapter that does all of that automatically:

This is the article that helped me do it, and it was VERY useful.
