I encountered a problem during development, and I need to go back to the login interface after changing the password. This requires closing all the previous activities, which is also very simple:
Add the following code to each activity:
private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { unregisterReceiver(this); // This sentence must be written or an error will be reported. Although it can be closed if not written, a bunch of errors will be reported. ((Activity) context).finish(); } }; @Override public void onResume() { super.onResume(); // Register the broadcast in the current activity IntentFilter filter = new IntentFilter(); filter.addAction("liu"); registerReceiver(this.broadcastReceiver, filter); // 注册 } public void close() { Intent intent = new Intent(); intent.setAction("liu"); // Description action sendBroadcast(intent);// This function is used to send broadcast finish(); }You can call the close() method on the button at the trigger time.
