  • Android为TV端助力 SharedPreferences 轻量级存储!

    首先在当前进程也就是当前的项目里面进行存储

    SharedPreferences.Editor editor = mContext.getSharedPreferences("tvplay", Context.MODE_PRIVATE).edit();
    editor.putString("video", content.getString("video"));
    editor.commit();

    这是存

    SharedPreferences preferences = getTargetContext().getSharedPreferences("tvplay", Context.MODE_PRIVATE);
    video = preferences.getString("video", "");

    这是取

    跨进程SharedPreferences进程存储

    SharedPreferences.Editor editor = mContext.getSharedPreferences("tvplay", Context.MODE_WORLD_READABLE).edit();
    editor.putString("video", content.getString("video"));
    editor.commit();

    这是存跟上面存唯一不同就是模式换了,不懂可以百度!

    private static final String TARGET_PACKAGE_NAME = "com.sdmc.hotel.ollauncher";// 目标数据程序的包名,

    SharedPreferences preferences = getTargetContext().getSharedPreferences("tvplay", Context.MODE_PRIVATE);
    video = preferences.getString("video", "");

    private Context getTargetContext(){
    try {
    return createPackageContext(TARGET_PACKAGE_NAME, Context.CONTEXT_IGNORE_SECURITY);
    } catch (NameNotFoundException e) {
    e.printStackTrace();
    }
    return null;
    }

    这是取,跟上面不同的就是要创建一个你要取的进程的context,然后在调用getSharedPreferences()方法
