有没有办法在snackBar上显示进度对话框,同时从服务器获取AsyncTask中的分页数据。如果可能,那么如何做到这一点。请给出建议。

对于新设计库:

如果你想在左侧显示progressBar:

 Snackbar bar = Snackbar.make(root, R.string.data_updating, Snackbar.LENGTH_INDEFINITE);
        ViewGroup contentLay = (ViewGroup) bar.getView().findViewById(android.support.design.R.id.snackbar_text).getParent();
        ProgressBar item = new ProgressBar(context);
        contentLay.addView(item,0);
        bar.show();

或右侧:

 Snackbar bar = Snackbar.make(root, R.string.data_updating, Snackbar.LENGTH_INDEFINITE);
        ViewGroup contentLay = (ViewGroup) bar.getView().findViewById(android.support.design.R.id.snackbar_text).getParent();
        ProgressBar item = new ProgressBar(context);
        contentLay.addView(item);
        bar.show();

最简单,最好的方法是:

Snackbar bar = Snackbar.make(layout, "Somthing", Snackbar.LENGTH_INDEFINITE);
Snackbar.SnackbarLayout snack_view = bar.getView();
snack_view.addView(new ProgressBar(context));
bar.show();

SnackbarLayout extends LinearLayout,因此您可以将视图添加为子视图或以您希望的方式对其进行自定义。

例如,要更改SnackBar中TextView的样式,您可以这样做:

TextView tv = (TextView) bar.getView().findViewById(android.support.design.R.id.snackbar_text);
tv.setTextColor(Color.WHITE);
tv.setTextSize(0, dimen[1] / 40);
tv.setTypeface(Typeface.createFromAsset(context.getAssets(),"fonts/font.otf"));

我已经写了一个可以做到这一点的图书馆。它还包括队列系统。试一试https://github.com/tingyik90/snackprogressbar

我认为您可以将自定义进度对话框设置为类似Snackbar,因为在加载时,snackbar不会阻止用户与GUI交互。

更新

试试这个:

创建anim res文件名为slide_in.xml并粘贴它:

<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromYDelta="50%p" android:toYDelta="0%p"
android:duration="@android:integer/config_longAnimTime"
/>

创建另一个动画res文件名为slide_out.xml:

<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="@android:integer/config_longAnimTime"
android:fromYDelta="0%p"
android:toYDelta="100%p" />

现在在样式res中放置进程对话框样式:

<style name="CustomDialog" parent="@android:style/Theme.Holo.Dialog">
    <item name="android:windowMinWidthMajor">100%</item>
    <item name="android:windowMinWidthMinor">100%</item>
    <item name="android:background">#323232</item>
    <item name="android:textColor">#FFFFFF</item>
    <item name="android:windowBackground">@color/transparent</item>
    <item name="android:backgroundDimEnabled">true</item>
    <item name="android:alertDialogStyle">@style/customDialogStyle</item>
    <item name="android:windowAnimationStyle">@style/DialogAnimation</item>

</style>

<style name="customDialogStyle">
    <item name="android:bottomBright">@android:color/transparent</item>
    <item name="android:bottomDark">@android:color/transparent</item>
    <item name="android:bottomMedium">@android:color/transparent</item>
    <item name="android:centerBright">@android:color/transparent</item>
    <item name="android:centerDark">@android:color/transparent</item>
    <item name="android:centerMedium">@android:color/transparent</item>
    <item name="android:fullBright">@android:color/transparent</item>
    <item name="android:fullDark">@android:color/transparent</item>
    <item name="android:topBright">@android:color/transparent</item>
    <item name="android:topDark">@android:color/transparent</item>

将其放置为动画:     

<style name="DialogAnimation">
    <item name="android:windowEnterAnimation">@anim/slide_in</item>
    <item name="android:windowExitAnimation">@anim/slide_out</item>
</style>

现在添加方法:

public static ProgressDialog processSnackbar(Context context,String s){
    ProgressDialog pSnackbar = new ProgressDialog(context, R.style.CustomDialog) {
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            ProgressBar progress = (ProgressBar) findViewById(android.R.id.progress);
            LinearLayout bodyLayout = (LinearLayout) progress.getParent();
            TextView messageView = (TextView) bodyLayout.getChildAt(1);

            messageView.setPadding(20,0,0,0);
            LinearLayout.LayoutParams llp =
                    (LinearLayout.LayoutParams) messageView.getLayoutParams();
            llp.width = 0;
            llp.weight = 1;


            bodyLayout.removeAllViews();
            bodyLayout.addView(messageView, llp);
            bodyLayout.addView(progress);
        }
    };
    pSnackbar.setProgressStyle(ProgressDialog.STYLE_SPINNER);
    pSnackbar.setMessage(s);
    pSnackbar.getWindow().setGravity(Gravity.BOTTOM);
    pSnackbar.setCancelable(false);
    return pSnackbar;
}

科特林 2021:

fun showLoadingSnackbar(){
    val snackbar: Snackbar = Snackbar.make(findViewById(R.id.rootlayoutid), "TEXT or RES", Snackbar.LENGTH_INDEFINITE)
    val viewGroup = snackbar.view.findViewById<View>(com.google.android.material.R.id.snackbar_text).parent as ViewGroup
    viewGroup.addView(ProgressBar(this))// Or Context if not in Activity
    snackbar.show()
}

如果你想要它在左边,只需调用 addView(ProgressBar(this),0) 而不是在另一个答案中提到

编辑:如果文本太长,答案会在顶部显示进度条,因此要使其居中,您可以这样做:

val snackbar: Snackbar = Snackbar.make(this, text, duration)
    val viewGroup = snackbar.view.findViewById<View>(com.google.android.material.R.id.snackbar_text).parent as ViewGroup
    viewGroup.addView(ProgressBar(context).also {
        it.layoutParams = ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.MATCH_PARENT)
        it.foregroundGravity = Gravity.CENTER_VERTICAL
    })
snackbar.show()
