问题描述
我试图创建一个系统的覆盖。不过,我不断收到权限被拒绝。我使用的SDK版本23。
我的清单文件:
< XML版本=1.0编码=UTF-8&GT?;
<舱单的xmlns:机器人=http://schemas.android.com/apk/res/android
包=com.test>
<使用-权限的Android:名称=android.permission.SYSTEM_OVERLAY_WINDOW/>
<应用
机器人:allowBackup =真
机器人:图标=@纹理映射/ ic_launcher
机器人:标签=@字符串/ APP_NAME
机器人:主题=@风格/ AppTheme>
<活动
机器人:名称=。activity.MainActivity
机器人:标签=@字符串/ APP_NAME>
<意向滤光器>
<作用机器人:名称=android.intent.action.MAIN/>
<类机器人:名称=android.intent.category.LAUNCHER/>
&所述; /意图滤光器>
< /活性GT;
< /用途>
< /舱单>
在code我用它来创建覆盖:
// MVIEW =新HUDView(本);
mButton =新的按钮(这一点);
mButton.setText(覆盖按钮);
mButton.setOnTouchListener(本);
WindowManager.LayoutParams PARAMS =新WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.RIGHT | Gravity.TOP;
params.setTitle(平均负载);
窗口管理WM =(窗口管理器)getSystemService(WINDOW_SERVICE);
wm.addView(mButton,则params);
首先,没有命名的权限 SYSTEM_OVERLAY_WINDOW
。这是 SYSTEM_ALERT_WINDOW
。
二,如果你的 targetSdkVersion
是23或更高,而你在Android 6.0+设备上运行,你的应用程序不会得到该许可在一开始就。呼叫 Settings.canDrawOverlays()
来看看,如果你有权限,并使用 ACTION_MANAGE_OVERLAY_PERMISSION
引领用户在设置如果你不知道。
I'm trying to create a system overlay. But I keep getting "permission denied". I'm using SDK version 23.
My manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.test" >
<uses-permission android:name="android.permission.SYSTEM_OVERLAY_WINDOW" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".activity.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
The code I use to create the overlay:
//mView = new HUDView(this);
mButton = new Button(this);
mButton.setText("Overlay button");
mButton.setOnTouchListener(this);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.RIGHT | Gravity.TOP;
params.setTitle("Load Average");
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
wm.addView(mButton, params);
First, there is no permission named SYSTEM_OVERLAY_WINDOW
. It is SYSTEM_ALERT_WINDOW
.
Second, if your targetSdkVersion
is 23 or higher, and you are running on Android 6.0+ devices, your app will not get this permission at the outset. Call Settings.canDrawOverlays()
to see if you have the permission, and use ACTION_MANAGE_OVERLAY_PERMISSION
to lead the user over to Settings if you do not.
