在Android中禁用屏幕锁定(电源)按钮

Question

我希望当我的应用程序运行电源按钮时(按下锁定屏幕和屏幕变黑),应该禁用.这样用户就无法锁定屏幕.

我在三星Galaxy S手机的默认相机应用程序中注意到了这一点.这与我试图做同样的事情是一样的.我还有一个相机相关的应用程序.

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();
            } 

这将关闭屏幕

在Android使用中禁用密钥保护

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

并使用permition

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

保持屏幕活着

 @Override
    protected void onCreate(Bundle icicle) {
        super.onCreate(icicle);

        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    }
