When you click the button as it appears in the code, the data in the edit text is added as a list view.
When I click the button, I want to add a random data from the listview items and add it in the textview.
public class MainActivity extends AppCompatActivity {
ListView listgor;
EditText textgir;
Button katgir;
Button kuraceker;
TextView katilimcisecer;
ArrayList<String> data = new ArrayList<String>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
data.add("Hello World");
listgor = (ListView) findViewById(R.id.listeler);
textgir = (EditText) findViewById(R.id.sira1);
katgir = (Button) findViewById(R.id.katilimciekle);
kuraceker = (Button) findViewById(R.id.kuracek);
katilimcisecer = (TextView) findViewById(R.id.katilimci) ;
listgor.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, data));
katgir.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View currentView) {
data.add(textgir.getText().toString());
textgir.setText("");
}
});
}
}
To add data from listview items to TextView
use code below.
int randomIndex = ThreadLocalRandom.current().nextInt(0, data.size())
yourTextView.setText(data.get(randomIndex))
