Ich habe eine Overlay-Schaltfläche in meiner Android-App. Ich möchte ein Layout anzeigen und mit den Ansichten meines Layouts interagieren, wenn der Benutzer auf die Schaltfläche klickt. Für den Moment zeige ich einen Toast. Wie kann ich das machen ?Ein Popup anzeigen, wenn Benutzer auf die Überlagerungsschaltfläche klicken
Das ist mein OverlayShowingService.class ist:
public class OverlayShowingService extends Service implements OnTouchListener, OnClickListener {
private View topLeftView;
private Button overlayedButton;
private float offsetX;
private float offsetY;
private int originalXPos;
private int originalYPos;
private boolean moving;
private WindowManager wm;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
overlayedButton = new Button(this);
overlayedButton.setText("Overlay button");
overlayedButton.setOnTouchListener(this);
overlayedButton.setBackgroundColor(Color.BLACK);
overlayedButton.setOnClickListener(this);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL, PixelFormat.TRANSLUCENT);
params.gravity = Gravity.LEFT | Gravity.TOP;
params.x = 0;
params.y = 0;
wm.addView(overlayedButton, params);
topLeftView = new View(this);
WindowManager.LayoutParams topLeftParams = new WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL, PixelFormat.TRANSLUCENT);
topLeftParams.gravity = Gravity.LEFT | Gravity.TOP;
topLeftParams.x = 0;
topLeftParams.y = 0;
topLeftParams.width = 0;
topLeftParams.height = 0;
wm.addView(topLeftView, topLeftParams);
}
@Override
public void onDestroy() {
super.onDestroy();
if (overlayedButton != null) {
wm.removeView(overlayedButton);
wm.removeView(topLeftView);
overlayedButton = null;
topLeftView = null;
}
}
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
float x = event.getRawX();
float y = event.getRawY();
moving = false;
int[] location = new int[2];
overlayedButton.getLocationOnScreen(location);
originalXPos = location[0];
originalYPos = location[1];
offsetX = originalXPos - x;
offsetY = originalYPos - y;
} else if (event.getAction() == MotionEvent.ACTION_MOVE) {
int[] topLeftLocationOnScreen = new int[2];
topLeftView.getLocationOnScreen(topLeftLocationOnScreen);
System.out.println("topLeftY="+topLeftLocationOnScreen[1]);
System.out.println("originalY="+originalYPos);
float x = event.getRawX();
float y = event.getRawY();
WindowManager.LayoutParams params = (LayoutParams) overlayedButton.getLayoutParams();
int newX = (int) (offsetX + x);
int newY = (int) (offsetY + y);
if (Math.abs(newX - originalXPos) < 1 && Math.abs(newY - originalYPos) < 1 && !moving) {
return false;
}
params.x = newX - (topLeftLocationOnScreen[0]);
params.y = newY - (topLeftLocationOnScreen[1]);
wm.updateViewLayout(overlayedButton, params);
moving = true;
} else if (event.getAction() == MotionEvent.ACTION_UP) {
if (moving) {
return true;
}
}
return false;
}
@Override
public void onClick(View v) {
Toast.makeText(this, "Here I want to show a layout with some options in a box", Toast.LENGTH_SHORT).show();
}
}
einfach mache einen anderen Dienst mit View und zeige ihn 'onClick' an –
Was hält dich davon ab, dieses Layout aufzublasen und es über' WindowManager # addView() 'hinzuzufügen, wie du es für diese Schaltfläche getan hast? – azizbekian
Wie folgt: wm.addView (MY_VIEW, params); ? Aber ich möchte ein Layout wie dieses R.layout.overlay einstellen. Wie kann ich das in View konvertieren? –
