Android listView中的简单搜索过滤

Question

我想在我的Android ListView中添加简单的搜索过滤器，就像这里一样：

Search.addTextChangedListener(new TextWatcher() {

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

            MainActivity.this.adapter.getFilter().filter(cs);
        }

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

        }

        @Override
        public void afterTextChanged(Editable arg0) {

        }
    });

此代码来自互联网上的教程（我丢失了一个网址）。它基于ArrayAdapter但在我的类中我使用的是SimpleCursorAdapter，这段代码不起作用。我的意思是我可以键入但不会过滤搜索结果。这是我的代码：

// Create the pointer to the desired data
        dataAdapter = new SimpleCursorAdapter(
                this, R.layout.contact_row, contactsCursor, columns, to, 0);
        ListView listView = (ListView) findViewById(R.id.list);
        Search = (EditText) findViewById(R.id.inputSearch); 

        Search.addTextChangedListener(new TextWatcher() {

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

                ContactListActivity.this.dataAdapter.getFilter().filter(cs);
            }

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

            }

            @Override
            public void afterTextChanged(Editable arg0) {

            }
        });

有没有办法在SimpleCursorAdapter上设置此过滤器功能？

Answer 1

Search.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence cs, int arg1, int arg2,
                int arg3) {
            String where = *YOURCOLUMN* + " LIKE '%" + cs + "%'";

            Cursor c = db.query(*TABLE*, *COLUMNS*, where, null, null, null, null);

            dataAdapter.swapCursor(c);
            dataAdapter.notifyDataSetChanged();
        }

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

        }

        @Override
        public void afterTextChanged(Editable arg0) {

        }
});

显然你需要输入你自己的数据，但大多数情况下应该做你想要的。希望它成功！
