As we know read data by Clipboard Manager in the background was stopped by Google in android Q, so I need anyway to paste data copied directly in edit text when a user returns to activity without user make a paste and without paste button.
The issue is that trying to read the data with getPrimaryClip()
returns null
.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_copy_and_paste);
ed_editText = findViewById(R.id.ed_editText);
}
@Override
protected void onResume() {
super.onResume();
getCopy()
}
private void getCopy() {
ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
if (clipboard != null && clipboard.hasPrimaryClip() && clipboard.getPrimaryClip() != null) {
CharSequence clip = clipboard.getPrimaryClip().getItemAt(0).coerceToText(CopyAndPasteActivity.this).toString();
ed_editText.setText(clip.toString());
}
}
XML
<EditText
android:id="@+id/ed_editText"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_marginLeft="24dp"
android:layout_marginStart="24dp"
android:maxLines="1"
android:lines="1"
android:focusable="true"
android:textSize="14sp"
android:inputType="text"
android:focusableInTouchMode="true"
android:layout_weight="1"
android:background="@null" >
<requestFocus />
</EditText>
You should access the clipboard in Window.Callback.onWindowFocusChanged(true)
, as that is the moment at which you gain input focus, which is required to read the clipboard in Android 10 (Q). You don't yet necessarily have input focus in onResume
.
