如何更改我的微调器后面的背景？

Question

我有使用eclipse创建的标准登录活动 新 - ＆gt;其他 - ＆GT; Android活动 - ＆gt;新登录活动

（您可以尝试创建相同的活动......我正在使用“Eclipse版本：Juno Service Release 1”）

我更改了所有背景活动/片段：＃0099cc

但是当我从一个活动转到另一个活动时，我会看到背景中的背景像白色一样。

你能帮助我吗？

我认为重要的代码如下：

showProgress（真）;

    /**
 * Shows the progress UI and hides the login form.
 */

@TargetApi(Build.VERSION_CODES.HONEYCOMB_MR2)
private void showProgress(final boolean show) {
    // On Honeycomb MR2 we have the ViewPropertyAnimator APIs, which allow
    // for very easy animations. If available, use these APIs to fade-in
    // the progress spinner.
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
        int shortAnimTime = getResources().getInteger(android.R.integer.config_shortAnimTime);

        mLoginStatusView.setVisibility(View.VISIBLE);

                    **I tried in this way**
        mLoginStatusView.setBackgroundColor(Color.parseColor("#0099cc"));
        mLoginStatusView.animate().setDuration(shortAnimTime).alpha(show ?1 : 0).setListener(new AnimatorListenerAdapter() {
        @Override
        public void onAnimationEnd(Animator animation) {
                        mLoginStatusView.setVisibility(show? View.VISIBLE : View.GONE); }
        });
        mLoginFormView.setVisibility(View.VISIBLE);
        mLoginFormView.animate().setDuration(shortAnimTime).alpha(show ? 0:1).setListener(new AnimatorListenerAdapter() {

        @Override
        public void onAnimationEnd(Animator animation) {
            mLoginFormView.setVisibility(show ? View.GONE:View.VISIBLE);
        }
                });
    } else {
        // The ViewPropertyAnimator APIs are not available, so simply show
        // and hide the relevant UI components.
        mLoginStatusView.setVisibility(show ? View.VISIBLE : View.GONE);
        mLoginFormView.setVisibility(show ? View.GONE : View.VISIBLE);
    }
}

在login.xml布局中

        <ProgressBar
        style="?android:attr/progressBarStyleLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="8dp"
        android:background="#0099cc" />

在attrs.xml中

<!--
     Declare custom theme attributes that allow changing which styles are
     used for button bars depending on the API level.
     ?android:attr/buttonBarStyle is new as of API 11 so this is
     necessary to support previous API levels.
-->
<declare-styleable name="ButtonBarContainerTheme">
    <attr name="buttonBarStyle" format="reference" />
    <attr name="buttonBarButtonStyle" format="reference" />
</declare-styleable>

Answer 1

我认为您需要为整个应用程序编写自己的样式，here是Google的API指南。

Answer 2

我解决了我的问题（在尝试以多种方式管理风格之后）添加一个简单的行：

getWindow（）getDecorView（）setBackgroundColor（Color.parseColor（ “＃0099CC”））;

    /**
     * Shows the progress UI and hides the login form.
     */
@TargetApi(Build.VERSION_CODES.HONEYCOMB_MR2)
private void showProgress(final boolean show) {
    // On Honeycomb MR2 we have the ViewPropertyAnimator APIs, which allow
    // for very easy animations. If available, use these APIs to fade-in
    // the progress spinner.

    getWindow().getDecorView().setBackgroundColor(Color.parseColor("#0099cc"));
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
        ...
