android - 膨胀底部导航 View 时出错

标签 android android-studio bottomnavigationview

它在我的 API 27 手机上工作正常，但在 API22 上崩溃

这是xml文件

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ReportsActivity">

<FrameLayout
    android:id="@+id/frame_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />

<android.support.design.widget.BottomNavigationView
    android:id="@+id/navigation"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"
    android:background="@color/bgBottomNavigation"
    app:itemBackground="@color/bgBottomNavigation"
    android:foreground="?attr/selectableItemBackground"
    app:itemIconTint="@color/nav_color"
    app:itemTextColor="@color/nav_color"
    app:menu="@menu/navigation" />

这是MainActivity文件

CoordinatorLayout容器；

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

    BottomNavigationView navigation = (BottomNavigationView) findViewById(R.id.navigation);
    navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
    requestPermission();


    loadFragment(new BranchVisitFragment());
}

@Override
public void onFragmentInteraction(Uri uri) {

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu, menu);
    return true;


@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    switch (item.getItemId()) {
        case R.id.menuLogout:

            FirebaseAuth.getInstance().signOut();
            finish();
            startActivity(new Intent(this, LoginActivity.class));

            break;

        case R.id.refresh:

            Fragment f = getSupportFragmentManager().findFragmentById(R.id.frame_container);
            if( f instanceof BranchVisitFragment)
                BranchVisitFragment.refresh();
            if(f instanceof GroupFragment)
                GroupFragment.refresh();
            break;

        case R.id.excel:

            Toast.makeText(this,"Creating the Excel Sheet...",Toast.LENGTH_LONG).show();
            CreateExcel.createExcel();
            break;

我觉得这个错误是由于这个文件引起的，但我不知道如何让这两个东西在 API22 中正常工作

这里是nav_color.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:color="#039BE5" />
    <item android:color="#616161"  />
</selector>

我已经在 stackoverflow 中寻找可能的解决方案，但我无法找到一个

这是gradle文件

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:support-v4:28.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.itextpdf:itextg:5.5.10'
implementation 'com.android.support:design:28.0.0'

这是错误:

最佳答案

经过12个小时的严谨思考和思考，我终于找到了解决方案。

我的代码绝对没有问题。

它在 drawable 文件夹中。

我将 2 个图标 PNG 放在 v24 可绘制文件夹中，结果它不适用于我检查过的 API23 和 API22。

所以只需将它们放回 Drawable 文件夹中，它就像一个魅力。

谢谢大家的帮助。
