禁用屏幕锁定（电源）按钮在安卓 [英] Disable Screen Lock(Power) Button in Android

问题描述

我想，当我的应用程序正在运行的电源按钮（在pressing锁定画面+屏幕变黑），应禁用。使得用户不能锁定屏幕。

I want that when my application is running the power button (which upon pressing locks the screen & screen goes BLACK), should be disabled. So that the user cannot lock the screen.

我已经注意到这件事情在三星Galaxy S手机的默认相机应用。这是同样的原因，我想这样做。我也有相​​关的应用程序中的摄像头。

I have noticed this thing in Samsung Galaxy S phone's Default Camera App. That's the same reason I am trying to do the same. I have also a Camera related App.

推荐答案

试试这个

int val=android.provider.Settings.System.getInt(getContentResolver(),
                                                                SCREEN_OFF_TIMEOUT);

                    android.provider.Settings.System.putInt(getContentResolver(),
                                                            SCREEN_OFF_TIMEOUT, -1);
                    Toast.makeText(this, "Disabled Screen Timeout", Toast.LENGTH_LONG).show();
                    SharedPreferences.Editor editor = settings.edit();
                    editor.putInt("ScreenTimeout",val);
                    editor.commit();
                }
            } catch(Throwable er) {
                Toast.makeText(this, "Error "+er.getMessage(), Toast.LENGTH_LONG).show();
            } 

这将设置屏幕关闭

禁用键后卫的Andr​​oid使用

to disable key guard in android use

KeyguardManager keyguardManager = (KeyguardManager)getSystemService(Activity.KEYGUARD_SERVICE);
KeyguardLock lock = keyguardManager.newKeyguardLock(KEYGUARD_SERVICE);
lock.disableKeyguard();

和使用permition

and use permition

<uses-permission android:name="android.permission.DISABLE_KEYGUARD"/>
