我在平板电脑(API 22)上设置Snackbar时出现问题,在手机(API 23和22)上设置正常(从边缘到边缘),即使在水平方向也是如此。 结果是如下Snackbar:enter image description here

FloatingActionButton(支持库)也不会移动(当它在手机上时)。

我的布局:

<?xml version="1.0" encoding="utf-8"?>
<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/snackParent"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:id="@+id/frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|right"
        android:layout_marginBottom="@dimen/margin_fab"
        android:layout_marginRight="@dimen/margin_fab"
        app:pressedTranslationZ="12dp" />
</android.support.design.widget.CoordinatorLayout>

在MainActivity中使用

private void showMessage(String msg) {
    if(snackParent != null) {
        snackbar = Snackbar.make(snackParent, msg, Snackbar.LENGTH_SHORT);
        snackbar.setAction("OK", new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                snackbar.dismiss();
            }
        });
        snackbar.show();
    }
}

我只有平板电脑尺寸(工厂边距)的其他资源文件(w820dp),手机和平板电脑之间的样式文件夹相同。我也试过使Android Studio缓存无效。 我使用com.android.support:design:23.0.1 targetSdkVersion = 23和compileSdkVersion = 23,buildToolsVersion = 23.0.1。

我认为这是平板电脑上零食吧的默认行为。检查this

答案 1 :(得分:1)

你可以用零食吧做任何你想做的事。我们在平板电脑上遇到了同样的问题,我们解决了这个问题(例如,下面的代码是在顶部定位零食店,并为其提供父母的全宽度)

View view = snackbar.getView();

// Position snackbar at top
FrameLayout.LayoutParams params = (FrameLayout.LayoutParams)view.getLayoutParams();
params.gravity = Gravity.TOP | Gravity.CENTER_HORIZONTAL;
params.width = FrameLayout.LayoutParams.MATCH_PARENT;
view.setLayoutParams(params);

答案 2 :(得分:0)

ViewGroup.LayoutParams layoutParams =快餐栏View.getLayoutParams();

        if (layoutParams instanceof FrameLayout.LayoutParams) {
            FrameLayout.LayoutParams params = (FrameLayout.LayoutParams) layoutParams;
            params.gravity = Gravity.TOP;
            params.width = FrameLayout.LayoutParams.MATCH_PARENT;
            snackbarView.setLayoutParams(params);
        } else if (layoutParams instanceof CoordinatorLayout.LayoutParams) {
            CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) layoutParams;
            params.gravity = Gravity.TOP;
            params.width = FrameLayout.LayoutParams.MATCH_PARENT;
            snackbarView.setLayoutParams(params);
        } else {
            FrameLayout.LayoutParams params = (FrameLayout.LayoutParams) layoutParams;
            params.gravity = Gravity.TOP;
            params.width = FrameLayout.LayoutParams.MATCH_PARENT;
            snackbarView.setLayoutParams(params);
        }
