屏蔽安卓系统Home键

Settings.System.putInt(getContentResolver(),"sys.home_key_to_app", 1);

Settings.System.putInt(getContentResolver(),"sys.home_key_to_app", 0);

     写字符串Settings.System.putString(ContentResolver resolver, String name, String value)

     读字符串Settings.System.getString(ContentResolver resolver, String name)

 

     写整型Settings.System.putInt(ContentResolver resolver, String name, int value)

     读整型Settings.System.getInt(ContentResolver resolver, String name，0)

说明:以上的值为为非1时代表，不屏蔽home键，为1时代表屏蔽home键;这种操作是修改安卓系统设置的数据库，需要申请权限的，在清单文件中声明：    

android:name="android.permission.WRITE_SETTINGS" />
android:name="android.permission.READ_SYNC_SETTINGS"/>

如果是6.0以上的手机需要：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

// 判断是否有WRITE_SETTINGS权限

if(!Settings.System.canWrite(this)) {

// 申请WRITE_SETTINGS权限

Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS, Uri.parse("package:" + getPackageName())); startActivityForResult(intent, REQUEST_CODE);

} else {

dosomething(); }

}

else { dosomething();

}

@Override

protected void onActivityResult(int requestCode, int resultCode, Intentdata) {

if (requestCode == REQUEST_CODE) {

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { // 判断是否有WRITE_SETTINGS权限

if (Settings.System.canWrite(this)) {

dosomething();

}

}

}

super.onActivityResult(requestCode, resultCode, data);

}

注：这样申请权限好像不起作用，它需要用户手动去开启权限

private String[] permissions = new String[]{

 Manifest.permission.WRITE_SETTINGS,

Manifest.permission.READ_SYNC_SETTINGS

};
