当使用Android WebView显示键盘时,BottomNavigationView会上升

Question

这个答案对WebViews不起作用,这也不适用.所以这个问题专门用于使用WebView时.下面的代码加载带有文本输入字段的网页.单击文本输入字段时,键盘出现.

public class MainActivity extends AppCompatActivity {

    @SuppressLint("SetJavaScriptEnabled")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

        final WebView webView = (WebView) findViewById(R.id.textFavorites);
        BottomNavigationView bottomNavigationView = (BottomNavigationView)
                findViewById(R.id.bottom_navigation);

        webView.loadUrl("https://www.journaldev.com");

        bottomNavigationView.setOnNavigationItemSelectedListener(
                new BottomNavigationView.OnNavigationItemSelectedListener() {
                    @Override
                    public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                        switch (item.getItemId()) {
                            case R.id.action_favorites:
                                webView.loadUrl("https://www.journaldev.com");
                                break;
                        }
                        return false;
                    }
                });
    }
}

activity_main.xml中:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <WebView
        android:id="@+id/textFavorites"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginBottom="?attr/actionBarSize"/>

    <android.support.design.widget.BottomNavigationView
        android:id="@+id/bottom_navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        app:itemBackground="@color/colorPrimary"
        app:itemIconTint="@color/white"
        app:itemTextColor="@color/white"
        app:menu="@menu/bottom_navigation_main" />

</RelativeLayout>

AndroidManifest.xml中:

    <activity
        android:name=".MainActivity"
        android:windowSoftInputMode="adjustPan">
    </activity>

bottom_navigation_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/action_favorites"
        android:enabled="true"
        android:icon="@drawable/ic_favorite_white_24dp"
        android:title="@string/text_favorites"
        app:showAsAction="ifRoom" />
</menu>

尝试在您的布局中使用此代码..我自己尝试过并且它有效...

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <WebView
        android:id="@+id/textFavorites"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginBottom="?attr/actionBarSize" />

    <android.support.design.widget.BottomNavigationView
        android:id="@+id/bottom_navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@id/textFavorites" // add this line to your code
        android:layout_alignParentBottom="true"
        app:itemBackground="@color/colorPrimary"
        app:itemIconTint="@color/white"
        app:itemTextColor="@color/white"
        app:menu="@menu/bottom_navigation_main" />

</RelativeLayout>

正如你所看到的，我android:layout_alignBaseline="@id/textFavorites"在底部导航视图中添加了这一行，它粘在底部......

并删除行 getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

但它也隐藏了文本字段......并将底部导航视图保留在键盘后面......
