I would like to implement a method that allows me to implement a listview with 2 different String-array from from strings.xml. My code works but my phone can only show the first 10 items. where is my problem? I f I try to run the code on a virtual device it works correctly.
Here is my code with only one textview. (this one shows only the first 10 items)
Button btt_backHome;
ListView lV_titoli;
EditText eT_search;
private ArrayAdapter<CharSequence> adapter , adapter_testi;
ImageView img_titoli;
List<RowData> rowData;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_titoli);
img_titoli = (ImageView) findViewById(R.id.img_titoli); // Create an icon
Picasso.get().load(R.drawable.sfondo).resize(2048, 1356).centerInside().into(img_titoli);
btt_backHome = (Button) findViewById(R.id.btt_backHome);
lV_titoli = (ListView) findViewById(R.id.lV_titoli);
eT_search = (EditText) findViewById(R.id.eT_search);
//serve per nascondere la tastiera
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
adapter = ArrayAdapter.createFromResource(this, R.array.titoli, android.R.layout.simple_list_item_1);
lV_titoli.setAdapter(adapter);
adapter.getFilter().filter("");
final Intent refresh = new Intent(this, activity_titoli.class);
final Intent to_Home = new Intent (this , Activity_Main.class);
final Intent to_Canzone_from_titoli = new Intent (this , activity_canzone.class);
eT_search.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) {
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
(activity_titoli.this).adapter.getFilter().filter(arg0);
}
});
btt_backHome.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
startActivity(to_Home);
}
});
lV_titoli.setOnItemClickListener(new AdapterView.OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Resources res = getResources();
List<String> list = Arrays.asList(res.getStringArray(R.array.titoli));
to_Canzone_from_titoli.putExtra("riga", list.indexOf(adapter.getItem(i)));
startActivity(to_Canzone_from_titoli);
}
});
}
And this is my xml code:
<ImageView
android:id="@+id/img_titoli"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:alpha="1"
android:scaleType="fitXY"
