setProgressBarIndeterminateVisibility（真）不工作 [英] setProgressBarIndeterminateVisibility(true) not working

问题描述

我想一个进度条添加到我的动作条。我说的是旋转圈。我做了一个请求，并试图建立是vissible，但没有任何反应。 我看过很多可能的问题，但仍无法弄清楚什么我做错了。

I'm trying to add a progress bar to my actionBar. I'm talking about the spinning circle. I did a request and tried to set is vissible, but nothing happens. I have read many likely questions but is still couldn't figure out what i'm doing wrong.

我的code：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    supportRequestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);//Above setContentView, very important
    setContentView(R.layout.activity_main);
    //...other stuff
}

在另一种方法，我不叫上创建。（这是一个onClick方法）

In an other method which i don't call in on create.(It's an onClick method)

public void plus(View view){
    setProgressBarIndeterminateVisibility(true);//Nothing happens
    //...other stuff
}

我不明白什么是错的，请帮助我。

I do not understand what's wrong, please help me.

注：我从来没有将其设置为false

NOTE: I never set it to false

编辑： 我试图mmlooloo第二部分，而且是绝对指出happend。即使不是第3部分。所以，我想第4部分，但我给了我一个例外。

I tried mmlooloo second part, but absolutly noting happend. Not even part 3. So I tried part 4, but i gave me an exception.

这个活动已经有靠窗户的装饰提供一个操作栏。   不要求Window.FEATURE_ACTION_BAR并设置windowActionBar为   假在主题用一个工具栏，而不是。

"This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead."

我删除了Window.FEATURE_ACTION_BAR请求，但它给了我同样的异常。 我不认为我需要设置windowActionBar为假，但我没有，它仍然给了我同样的例外。

I removed the Window.FEATURE_ACTION_BAR request, but it gave me the same exception. I don't think i need to set windowActionBar to false, but I did and it still gave me the same exception.

任何其他的选择吗？

推荐答案

设置窗口进度条pcated与工具栏现在去$ P $。

First:

您必须使用：

Second:

you must use:

而不是

setProgressBarIndeterminateVisibility(true);

因为你伸出 ActionBarActivity 。 （因为你使用 supportRequestWindowFeature 而不是 requestWindowFeature ）

because you extends ActionBarActivity. (because you are using supportRequestWindowFeature instead of requestWindowFeature)

如果它崩溃，这是一个已知的问题。 如果你的库更新，抱歉，但它现在只是一个空操作：

If it crashes this is a known issue. If your library is updated sorry but it is now just a no-op:

setSupportProgressBarIndeterminateVisibility（）崩溃已得到修复   在以后的版本中，这将是一个空操作。

setSupportProgressBarIndeterminateVisibility() crashing has been fixed for a future release, in that it will be a no-op.

我的解决办法：

使用工具栏进度部件：

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        ProgressBar progressBar = (ProgressBar) findViewById(R.id.progress_spinner);
        progressBar.setVisibility(View.VISIBLE);
    }

布局：

activity_main.xml

activity_main.xml

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

    <include layout="@layout/toolbar"/>

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

</LinearLayout>

和

toolbar.xml

toolbar.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <ProgressBar
        android:id="@+id/progress_spinner"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:indeterminate="true"
        android:visibility="gone" />

</android.support.v7.widget.Toolbar>
