Android工具栏后退箭头不可点击

Question

我真的尝试了一切，试图让我的背向箭头在我的工具栏上工作，但我没有成功。我尝试了覆盖选项ItemSelected。我还尝试了这个线程导航的建议（操作栏的背向箭头）不适用于片段，也没有成功。我也在处理碎片。

注册表活动

public class RegisterActivity extends AppCompatActivity implements View.OnClickListener {

private Toolbar toolbar;

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.activity_register);
    ButterKnife.bind(this);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDisplayShowHomeEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);
}

@Override
public void onClick(View view) {
    switch (view.getId()) {
        case ( R.id.button_accept_tos ) :
            /*
            Fragment inputUserFragment = new AcceptAgreementFragment();
            FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
            transaction.setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out);
            transaction.replace(R.id.main_activity, inputUserFragment);
            transaction.addToBackStack(null);
            transaction.commit();
            */
            break;
    }
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            onBackPressed();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

显示

 <application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".activity.MainActivity"
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".activity.RegisterActivity"
        android:windowSoftInputMode="adjustPan|adjustResize"
        android:screenOrientation="portrait">
    </activity>

    <meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value=".activity.MainActivity"
        />

</application>

和我的activity\u注册xml

    <?xml version="1.0" encoding="utf-8"?>

    xmlns:tools="http://schemas.android.com/tools"

        android:id="@+id/toolbar"

        android:layout_height="wrap_content"
        app:titleTextColor="@android:color/white"
        app:navigationIcon="@drawable/ic_arrow_back_white_24dp"

            android:layout_gravity="center"
            />

    </android.support.v7.widget.Toolbar>



    <!--wizard>-->

Answer 1

将其添加到清单活动中

android:theme="@style/AppTheme.NoActionBar">

您的样式文件必须如下所示

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

Answer 2

试试这个。。。

在活动（清单）中使用此主题

<style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
</style>

在您的活动中

Toolbar toolbar;

//on创建

toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

然后为工具栏调用setNavigationOnClickListener

toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                onBackPressed();
            }
        });

现在检查onClick on Back按钮。。。
