Android工具栏返回箭头不可单击

我已经尝试了一切，试图让我的返回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，我也尝试了这个线程上的建议，但没有成功。我也在处理碎片

注册活动

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);
    }
}

将其添加到您的清单活动中

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" />

假的
真的

试试这个

在活动（清单）中使用此主题

//一次创建

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

然后调用工具栏的setNavigationOnClickListener

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

---

现在检查onClick on Back按钮…

您的

onClick

方法是否被调用过？（猜测注释掉的是调试结果）@Phix是的called@user8924538您解决了吗…？@user8924538您是否覆盖了

onBackPressed

并删除了

super.onBackPressed（）？如果你那样做了，这就行不通了
toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

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