在Android的ListView的简单搜索过滤 [英] Simple search filtering in Android listView
问题描述
我想在我的Android ListView控件添加简单的搜索过滤器，就像这里：
Search.addTextChangedListener（新TextWatcher（）{ @覆盖
公共无效onTextChanged（CharSequence的CS，INT ARG1，ARG2 INT，
INT ARG3）{ 。MainActivity.this.adapter.getFilter（）过滤器（CS）;
} @覆盖
公共无效beforeTextChanged（CharSequence的为arg0，ARG1 INT，
INT ARG2，诠释ARG3）{ } @覆盖
公共无效afterTextChanged（编辑为arg0）{ }
}）;
这code是从互联网上找到的教程（我已经失去了一个URL）。它是基于ArrayAdapter，但在我的课我使用SimpleCursorAdapter这code不起作用。我的意思是我可以输入，但它不会过滤搜索结果。这里是我的code：
//创建指向所需的数据
DataAdapter的=新SimpleCursorAdapter（
此，R.layout.contact_row，contactsCursor，列，向，0）;
ListView控件的ListView =（ListView控件）findViewById（R.id.list）;
搜索=（EditText上）findViewById（R.id.inputSearch）; Search.addTextChangedListener（新TextWatcher（）{ @覆盖
公共无效onTextChanged（CharSequence的CS，INT ARG1，ARG2 INT，
INT ARG3）{ 。ContactListActivity.this.dataAdapter.getFilter（）过滤器（CS）;
} @覆盖
公共无效beforeTextChanged（CharSequence的为arg0，ARG1 INT，
INT ARG2，诠释ARG3）{ } @覆盖
公共无效afterTextChanged（编辑为arg0）{ }
}）;
有什么办法来设置SimpleCursorAdapter此过滤器功能？
Search.addTextChangedListener（新TextWatcher（）{ @覆盖
公共无效onTextChanged（CharSequence的CS，INT ARG1，ARG2 INT，
INT ARG3）{
字符串，其中* = * YOURCOLUMN +LIKE'％+ CS +％'; 光标C = db.query（*表，*柱*，其中，NULL，NULL，NULL，NULL）; dataAdapter.swapCursor（C）;
dataAdapter.notifyDataSetChanged（）;
} @覆盖
公共无效beforeTextChanged（CharSequence的为arg0，ARG1 INT，
INT ARG2，诠释ARG3）{ } @覆盖
公共无效afterTextChanged（编辑为arg0）{ }
}）;
显然，你要去需要把自己的数据，但在大多数情况下应该做你想要什么。希望它的作品了！
I want to add simple search filter in my Android ListView just like here :
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) {
}
});
This code is from tutorial found in the internet (I have lost an url). It is based on ArrayAdapter but in my class I am using SimpleCursorAdapter and this code doesn't work. I mean I can type but it won't filter search results. Here is my code :
// 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) {
}
});
Is there any way to set this filter function on SimpleCursorAdapter?
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) {
}
});
Obviously your gonna need to put in your own data, but for the most part that should do what you want. Hope it works out!
