首先,我是一个初学者,所以请在这里忍受一会儿。
我正在尝试创建包含项目列表的应用。当您单击该项目时,将转到一个新的相应活动。当我添加SearchView来过滤列表项时,单击过滤后的结果现在出现问题,它们不直接指向相应的活动。
您能否在下面更正我的代码,或者提供一种更好的方法来直接进行相应的活动。请提供尽可能详细的信息。提前非常感谢。
MainActivity.java
public class MainActivity extends Activity
implements SearchView.OnQueryTextListener {
private SearchView mSearchView;
private ListView mListView;
private final String[] mStrings = { "Google", "Apple", "Samsung", "Sony", "LG", "HTC" };
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
setContentView(R.layout.activity_main);
mSearchView = findViewById(R.id.search_view);
mListView = findViewById(R.id.list_view);
mListView.setAdapter(new ArrayAdapter<>(this,
android.R.layout.simple_list_item_1,
mStrings));
mListView.setTextFilterEnabled(true);
setupSearchView();
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (position == 0) {
Intent i = new Intent(MainActivity.this, google.class);
startActivity(i);
} else {
// code to direct to the corresponding activity
}
});
}
private void setupSearchView() {
mSearchView.setIconifiedByDefault(false);
mSearchView.setOnQueryTextListener(this);
mSearchView.setSubmitButtonEnabled(true);
mSearchView.setQueryHint("Search Here");
}
public boolean onQueryTextChange(String newText) {
if (TextUtils.isEmpty(newText)) {
mListView.clearTextFilter();
} else {
mListView.setFilterText(newText);
}
return true;
}
public boolean onQueryTextSubmit(String query) {
return false;
}
}
if (position == 0) {
Intent i = new Intent(MainActivity.this, google.class);
startActivity(i);
} else if ( position == 1){
// do something, sending to activity of choice
} else if ( position == 2){
// do something , sending to activity of choice
}
针对您想要进行多少种不同的活动重复此操作。
