     return super.onOptionsItemSelected(item); 
    } 
} 

folgend ist der Code, zum meiner Liste ITEMS anzuzeigen. Ich wollte meine fünfte Zeile item d. H. UPI aktiviert kopieren, wenn lange gedrückt wird. Wie mache ich das? Bitte bearbeite meinen Code, damit das Gleiche passiert.

Answer 1

Veränderung der Layout-Datei: fügen Sie die folgende Eigenschaft auf Ihre TextView:

android:textIsSelectable="true" 

ODER

in Ihrer Java-Klasse schreiben Sie diese Zeile es programmatisch zu setzen:

myTextView.setTextIsSelectable(true); 

Text kopieren :

tv.setOnLongClickListener(new View.OnLongClickListener() { 

    @Override 
    public boolean onLongClick(View v) { 
     ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); 
     ClipData clip = ClipData.newPlainText("", tv.getText()); 
     clipboard.setPrimaryClip(clip); 
     Toast.makeText(context, "Copied to clipboard", Toast.LENGTH_SHORT).show(); 
     return true; 
    } 
}); 

Vergewissern Sie sich, dass Sie android.content.ClipboardManager und NICHT android.text.ClipboardManager importiert haben.

Answer 2

Fügen Sie in Ihrem row_layout für Ihre ListView einfach die Eigenschaft android:textIsSelectable der TextView hinzu, auf der kopiert werden soll.
