Android禁用home/recent键的方法

禁用home/recent键步骤如下，成功调用的前提是app要系统签名（platform key）

1. 定义flags变量如下

public static final int DISABLE_NONE =0x00000000;

public static final int DISABLE_HOME =0x00200000;

public static final int DISABLE_RECENT =0x01000000;

public static final int DISABLE_EXPAND =0x00010000;

2. 在onWindowFocusChanged方法中调用disableStatusBar

@Override

public void onWindowFocusChanged(boolean hasFocus) {

super.onWindowFocusChanged(hasFocus);

disableStatusBar(DISABLE_HOME |DISABLE_RECENT |DISABLE_EXPAND);

}

3. 在onStop中还原status bar状态，在定要还原，否则系统无法正常使用。

@Override

protected void onStop() {

super.onStop();

Log.e(TAG,"#################onStop");

disableStatusBar(DISABLE_NONE);

}

public void disableStatusBar(int flags) {

try {

Object service = getSystemService("statusbar");

Class statusBarManager = Class.forName("android.app.StatusBarManager");

Method disable = statusBarManager.getMethod("disable",int.class);

disable.invoke(service, flags);

}catch (Exception e) {

Log.e(TAG,"#################disable error:", e);

}

}
