In my code, searching for a word can be found very well,
But unfortunately, searching for two words or more doesn't work.
How to search a sentence (two words and more) in android programming?
My Java code:
public class MainActivity extends Activity {
EditText etSearchKey;
private ListView contentListView;
private database db;
private List<HashMap<String, Object>> books_list;
private List<HashMap<String, Object>> resultBooks;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list_hezb);
contentListView = (ListView) findViewById(R.id.tblhezb);
etSearchKey = (EditText) findViewById(R.id.txthezb);
db = new database(getBaseContext());
db.open();
Bundle data = getIntent().getExtras();
books_list = db.getItem(data.getString("sea"));
String[] from = {"name"};
int[] to = {R.id.row_hezb_name};
SimpleAdapter adb = new SimpleAdapter(getBaseContext(), books_list,
R.layout.row_hezb, from, to) {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
return view;
}
};
contentListView.setAdapter(adb);
db.close();
etSearchKey.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
etSearchKey.setFocusableInTouchMode(true);
etSearchKey.requestFocus();
InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.showSoftInput(etSearchKey, InputMethodManager.SHOW_FORCED);
}
});
etSearchKey.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
String search_by = "name";
if (etSearchKey.getText().length() < 1) {
return;
}
String key = etSearchKey.getText().toString().trim();
String[] keys = key.split("\\s+");
String query = search_by + " LIKE '%" + keys[0] + "%'";
StringBuilder sb = new StringBuilder();
for (int i = 1; i < keys.length; i++) {
sb.append(" OR " + search_by + " LIKE '%" + keys[i] + "%'");
}
query = query + sb.toString();
showResultOfSearch(query);
}
});
contentListView
.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent i = new Intent(getBaseContext(),
List_hezbha.class);
String my_id = books_list.get(position).get("name")
.toString();
i.putExtra("name", my_id);
startActivity(i);
}
});
}
public void showResultOfSearch(String query) {
db.open();
contentListView.setAdapter(null);
resultBooks = db.getTableOfResultsOfSearchhezb(query);
db.close();
if (resultBooks.size() < 1) {
return;
}
String[] from = {"name"};
int[] to = {R.id.row_hezb_name};
SimpleAdapter adb = new SimpleAdapter(
getBaseContext(), resultBooks,
R.layout.row_hezb, from, to
) {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
return view;
}
};
contentListView.setAdapter(adb);
contentListView.setOnItemClickListener(
new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
try {
etSearchKey.setText("");
etSearchKey.clearFocus();
Intent i = new Intent(getBaseContext(), List_hezbha.class);
String my_id = resultBooks.get(position).get("name").toString();
i.putExtra("name", my_id);
startActivity(i);
} catch (Exception ex) {
}
}
}
);
}
}

Android ListView is a view which groups several items and display them in vertical scrollable list. The list items are automatically inserted to the list using an Adapter that pulls content from a source such as an array or database. I’d appreciate your cooperation.
