Is there any way to show a modeless dialog--a dialog that allows the user to interact with whatever was on the screen before the dialog but also allows the user to interact with the dialog if pressed?
I know of Toasts, but they don't allow interaction with the popup.
I know of Dialogs, but they're modal and don't allow interaction with the background.
I know of Notifications, but I want something that is visibile on screen.
I basically want to be able to be playing a game or something and a popup appears that I have a new email or something. I can click it to view my email, but I can wait for it to go away if I just want to continue playing my game. Is this possible in Android?
Yes, create an Activity with style Theme.Dialog
. This is a normal activity which looks like a dialog, while being modeless and accepting events.
An example:
<activity android:name=".activity.dialog.PhotoDialog"
android:label="@string/photo_dialog_title"
android:theme="@android:style/Theme.Dialog"/>
Edited:
Indeed Theme.Dialog
blurs the underlying activity and makes it unaccessible. I had a similar requirement here I had to show upload progress dialog with text and cancel button. The main catch is in setting WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
and resetting WindowManager.LayoutParams.FLAG_DIM_BEHIND
.
Created a Dialog with custom content:
if (progressDialog == null) {
progressDialog = new Dialog(activityRequestingProgressDialog);
progressDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
progressDialog.setContentView(R.layout.progress_upload);
progressBar = (ProgressBar) progressDialog.findViewById(R.id.progressBar);
progressText = (TextView) progressDialog.findViewById(R.id.progressText);
progressText.setText("0 %");
progressText.setTextSize(18);
Button buttonCancel = (Button) progressDialog.findViewById(R.id.btnCancel);
buttonCancel.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
cancelProgressDialog();
stopUpload("Upload cancelled.");
}
});
Window window = progressDialog.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
window.setGravity(Gravity.BOTTOM);
progressDialog.show();
}
progressText.setText(text);
progressBar.setProgress(percent);
And this is the layout for this Dialog:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/progressDialog"
android:orientation="vertical"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_centerVertical="true">
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:textSize="18sp"
android:padding="10dp"
android:text="@string/progress_title"/>
<LinearLayout android:id="@+id/progressDialog"
android:orientation="horizontal"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:padding="10dp"
android:layout_centerVertical="true">
<ProgressBar android:id="@+id/progressBar"
android:layout_width="150dp"
android:layout_height="34dp"
android:paddingRight="10dp"
android:max="100"
android:progress="0"
android:fadingEdge="vertical"
style="?android:attr/progressBarStyleHorizontal"/>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="@+id/progressText"
android:paddingRight="10dp"/>
<Button android:layout_height="40dp"
android:layout_width="80dp"
android:id="@+id/btnCancel"
android:text="@string/dialog_cancel"/>
</LinearLayout>
</LinearLayout>
