请检查给定的代码.

我遇到问题引起:

我是android开发的新手.我希望在用户未登录时隐藏导航抽屉.所以基本上,它会显示登录片段(更好的全屏幕像Facebook android).如果用户已登录,将始终显示导航抽屉.

MainActivity.java

public class MainActivity extends AppCompatActivity {

private DrawerLayout navDrawerLayout;
private Toolbar toolbar;
private ActionBarDrawerToggle navDrawerToggle;

private SharedPreferences pref;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    navDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

    // Find our drawer view
    NavigationView navDrawerView = (NavigationView) findViewById(R.id.navdrawer_view);
    // Setup drawer view
    setupDrawerContent(navDrawerView);

    navDrawerToggle = setupDrawerToggle();

    pref = getPreferences(0);
    initFirstFrame();
}

private ActionBarDrawerToggle setupDrawerToggle() {
    return new ActionBarDrawerToggle(this, navDrawerLayout, toolbar, R.string.drawer_open,  R.string.drawer_close);
}

private void setupDrawerContent(NavigationView navDrawerView) {
    navDrawerView.setNavigationItemSelectedListener(
            new …

String value = myInput.getText().toString();

我想将字符串值放入JSONObject.put("STRING",value)方法中，但它不起作用。

请参阅随附的屏幕截图并了解如何解决此问题。

我的代码是，

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {\n        Bitmap bm = BitmapFactory.decodeResource(context.getResources(),R.drawable.app_icon);\n        ActivityManager.TaskDescription taskDescription = new ActivityManager.TaskDescription("AppName", bm ,R.color.colorPrimaryDark);\n        setTaskDescription(taskDescription);\n    }\n

在colors.xml

<color name="colorPrimaryDark">#FF9800</color> \n

它给出了错误java.lang.RuntimeException: A TaskDescription\'s primary color should be opaque

我制作了一个具有后台服务和广播接收器的应用程序，而我的应用程序包含MainActivity.java和myServiceRunner.java。当我启动后台服务时，它给我这个错误android.content.res.Resources$NotFoundException: String resource id #0x64。

我将这些代码放在受保护的void onCreate（Bundle savedInstanceState）中：

     IntentFilter mainFilter=new IntentFilter("liren.action.GOSERVICE3");
      receiver=new MyMainLocalReceiver();
      registerReceiver(receiver, mainFilter);

MyMainLocalReceiver.java

   public class MyMainLocalReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {

        try
        {
            int serviceData=intent.getIntExtra("serviceData",0);
            //Toast.makeText(getApplicationContext(), serviceData,Toast.LENGTH_SHORT).show();

            tvStepsCount.setText(serviceData);
        }
        catch (Exception e)
        {
            tvStepsCount.setText(e.toString());
        }

    }
}

在myServiceRunner扩展Service类内部，我已在onStartCommand方法中添加了这些代码。

  @Override
   public int onStartCommand(Intent intent, int flags, int startId) {
    Thread triggerService=new Thread(new Runnable() {
        @Override
        public void run() {
            for(;;)
            {
                try
                {
                    Intent myFilteredResponse = new …
