Appcompatv7-v21 탐색 창에 햄버거 아이콘이 표시되지 않음

Appcompatv7-v21 탐색 창에 햄버거 아이콘이 표시되지 않음

---

최신 appcompat 지원 라이브러리로 롤리팝 스타일 탐색 서랍을 구현하고 있지만 문제는 햄버거 아이콘이 표시되지 않는다는 것입니다. 뒤로 아이콘 만 표시됩니다.

이것은 내 활동 코드입니다.

import android.os.Bundle;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.widget.Toolbar;
import android.view.View;

public class Home extends ActionBarActivity {

private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;

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


private void initViews(){

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);


    toolbar.setTitleTextColor(getResources().getColor(android.R.color.white));
    setSupportActionBar(toolbar);

    mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,toolbar ,  R.string.drawer_open, R.string.drawer_close) { 

        /** Called when a drawer has settled in a completely closed state. */ 
        public void onDrawerClosed(View view) {
            super.onDrawerClosed(view);
            //getActionBar().setTitle(mTitle);
            //invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
        } 

        /** Called when a drawer has settled in a completely open state. */ 
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
            //getActionBar().setTitle(mDrawerTitle);
            //invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
        } 
    }; 


    // Set the drawer toggle as the DrawerListener 
    mDrawerLayout.setDrawerListener(mDrawerToggle);

    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
    getSupportActionBar().setHomeButtonEnabled(true); 

 }
}

이것은 내 스타일 파일입니다.

두 경우 모두 뒤로 화살표 만 표시되고 많은 게시물을 읽었지만 아무런 차이가없는 것 같습니다. 어떤 도움을 주시면 감사하겠습니다.

---

당신은 전화해야합니다

mDrawerToggle.syncState();

---

올바른 서랍 토글을 가져오고 있는지 확인하십시오.

v4 버전을 가져올 때 화살표 (아래)가있었습니다.

import android.support.v4.app.ActionBarDrawerToggle;

이것을 (아래, v7) 변경하면 내 문제가 해결되었습니다.

import android.support.v7.app.ActionBarDrawerToggle;

---

ActionBarDrawerToggle을 사용하는 경우 onPostCreate () 및 onConfigurationChanged () 중에 호출해야합니다.

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        // Sync the toggle state after onRestoreInstanceState has occurred.
        mDrawerToggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        // Pass any configuration change to the drawer toggls
        mDrawerToggle.onConfigurationChanged(newConfig);
    }

---

전화했는지 확인하십시오.

mDrawerToggle.syncState();

전화 후

getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
getSupportActionBar().setHomeButtonEnabled(true); 

---

Since my NavigationDrawer was extending a Fragment not an Activity I was not able to override postCreate. The below is what I did.

   ActionBar actionBar = getActionBar();
   actionBar.setDisplayHomeAsUpEnabled(true); // this sets the button to the    back icon
   actionBar.setHomeButtonEnabled(true); // makes it clickable
   actionBar.setHomeAsUpIndicator(R.drawable.ic_drawer);// set your own icon

Hope it helps!

Dont forget to override onOptionsItemSelected method and check if ctionBarDrawerToggle was clicked, in this case return true otherwise the activity will be finished.

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (actionBarDrawerToggle.onOptionsItemSelected(item)) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

---

You can simply use this:

// Defer code dependent on restoration of previous instance state.
mDrawerLayout.post(new Runnable() {
    @Override
    public void run() {
        mDrawerToggle.syncState();
        getActionBar().setHomeAsUpIndicator(R.drawable.ic_drawer);
    }
});

---

mDrawerToggle.syncState() did not work for me, but I eventually got it to work with:

getSupportActionBar().setHomeAsUpIndicator(R.drawable.hamburger_icon);

I was, however, not using a Toolbar.

---

While including ActionBarDrawerToggle, make sure to use the post method:

mDrawerLayout.post(new Runnable() {
   @Override
   public void run() {
       mDrawerToggle.syncState();
   }
});

---

I also got similar problem, in my case problem was, when initiating actionbartoggle, I was not passing valid toolbar argument (toolbar was initialized later), without a proper, non-null toolbar, ActionBarToggle will fail to create a hamburger icon.

actionBarToggle = ActionBarDrawerToggle(this, mDrawer, toolbar, 
R.string.drawer_open, R.string.drawer_close);

---

onRestoreInstanceState가 발생한 후 활동의 onPostCreate에서 syncState ()를 호출하여 인디케이터를 연결된 DrawerLayout의 상태와 동기화 할 수 있습니다.

@Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        // Sync the toggle state after onRestoreInstanceState has occurred.
        mDrawerToggle.syncState();
    }

또한 ActionBarDrawerToggle을 DrawerLayout.DrawerListener로 직접 사용할 수 있습니다. 이미 자체 리스너를 제공하고있는 경우 각 리스너 메소드를 직접 호출 할 수 있습니다.

private ActionBarDrawerToggle mDrawerToggle;
private DrawerLayout mDrawerLayout;
  .
  .
  .
  .
mDrawerLayout.setDrawerListener(mDrawerToggle);

    mDrawerLayout.post(new Runnable() {
        @Override
        public void run() {
            mDrawerToggle.syncState();
        }
    });

작업 표시 줄 메뉴를 클릭 할 때 탐색 창이 표시되지 않았습니다. 이것은 나를 위해 그것을 고쳤습니다.

   @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (mDrawerToggle.onOptionsItemSelected(item)) {
            return true;
        }
      //add your switch statement


        return super.onOptionsItemSelected(item);
    }

---

이것은 나를 위해 작동합니다. ActionBarActivity 대신 AppCompatActivity를 확장했습니다.

mActionBarDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,null, R.string.drawer_opened, R.string.drawer_closed) {
    @Override
    public void onDrawerOpened(View drawerView) {
        super.onDrawerOpened(drawerView);
        if( getSupportActionBar()!= null)
        getSupportActionBar().setTitle(R.string.drawer_opened);
        mActionBarDrawerToggle.syncState();
    }

    @Override
    public void onDrawerClosed(View drawerView) {
        super.onDrawerClosed(drawerView);
        if(getSupportActionBar() != null)
            getSupportActionBar().setTitle(R.string.drawer_closed);
            mActionBarDrawerToggle.syncState();

    }
};
