更改进度的Andr​​oid半透明的背景颜色 [英] Changing translucent background color of progressbar android

问题描述

我想换有黑色半透明背景，不透明度小于50％的进度的背景色。 我搜索了很多关于这一点，但没能找到解决方案。 我不知道我是否正确与否，但它有一些事情与进度的mdecor属性。

I want to change background color of the progressbar having black translucent background with opacity less than 50%. I searched a lot about this but not able to find solution. I don't know whether i'm right or not but it has some thing to do with mdecor property of the progressbar.

以下是code我使用它。

Following is the code I am using it.

pd = ProgressDialog.show(getActivity(), null, null,true);       
pd.setContentView(R.layout.remove_border);

在$ C $下删除边框布局是：

The code for remove border layout is:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/transparent"
android:orientation="vertical" >

<ProgressBar
    android:id="@+id/progressBar1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:background="@android:color/transparent"
    android:indeterminateDrawable="@drawable/my_progress_indeterminate" />

</LinearLayout>

在$ C $下my_progress_indeterminate是：

The code for my_progress_indeterminate is:

<animated-rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="@drawable/loadingiconblack"
android:pivotX="50%"
android:pivotY="50%" />

以下是背景区域被标记为红色圆圈的图像。我想改变颜色为白色与同不透明性。

Following is the image the background area is marked in red circle. I want to change color to white with same opacity.

编辑：

最终解决我到Sripathi发行的感谢和user3298272这两种解决方案在这里结合我更新的答案：

pd = new Dialog(this, android.R.style.Theme_Black);
View view = LayoutInflater.from(this).inflate(R.layout.remove_border, null);
pd.requestWindowFeature(Window.FEATURE_NO_TITLE);
pd.getWindow().setBackgroundDrawableResource(R.color.transparent);
pd.setContentView(view);
pd.show();

remove_border XML code： 在这里，Android的：重力=中心在我的线性布局code添加

remove_border xml code: Here android:gravity = "center" is added in linear layout code of mine.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/transparent"
android:gravity="center"
android:orientation="vertical" >

<ProgressBar
    android:id="@+id/progressBar1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:background="@android:color/transparent"
    android:indeterminateDrawable="@drawable/my_progress_indeterminate" />

</LinearLayout>

色XML code：

color xml code:

<resources>

  <color name="transparent">#80FFFFFF</color>

</resources>

在＃80FFFFFF 80是不透明度值50％，这是我从user3298272了。

In #80FFFFFF 80 is the opacity value 50% which i took from user3298272.

推荐答案

您可以用对话代替progressdialog，

You can use dialog instead of progressdialog,

    dialogTransparent = new Dialog(this, android.R.style.Theme_Black);
    View view = LayoutInflater.from(getActivity()).inflate(
            R.layout.remove_border, null);
    dialogTransparent.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialogTransparent.getWindow().setBackgroundDrawableResource(
            R.color.transparent);
    dialogTransparent.setContentView(view);

更新：

   Here the color transparent is  #80FFFFFF
