Android中如何设置ProgressDialog的颜色和背景
String.xml 文件，progressDialog是继承与Dialog，先设置一下progressDialog的风格，设置你想要的背景和颜色：
<style name="CustomDialog" parent="@android:style/Theme.Dialog">
<item name="android:windowFrame">@null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
<item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
</style>
<style name="CustomProgressDialog" parent="@style/CustomDialog">
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowNoTitle">true</item>
</style>
2.customprogressdialog.xml文件，定义自己的布局，由于我的需求只需要一个进度条以及一串显示的内容，所以布局比较接单
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal">
<ImageView
android:id="@+id/loadingImageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@anim/progress_round"/>
<TextView
android:id="@+id/id_tv_loadingmsg"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:textSize="20dp"/>
</LinearLayout>
3.progress_round.xml文件.这个文件为了实现转动的效果，循环显示这些图片。
<?xml version="1.0" encoding="utf-8"?>
<animation-list
android:oneshot="false">
<item android:drawable="@drawable/progress_1" android:duration="200"/>
<item android:drawable="@drawable/progress_2" android:duration="200"/>
<item android:drawable="@drawable/progress_3" android:duration="200"/>
<item android:drawable="@drawable/progress_4" android:duration="200"/>
<item android:drawable="@drawable/progress_5" android:duration="200"/>
<item android:drawable="@drawable/progress_6" android:duration="200"/>
<item android:drawable="@drawable/progress_7" android:duration="200"/>
<item android:drawable="@drawable/progress_8" android:duration="200"/>
</animation-list>
4.CustomProgressDialog.java文件，这个是就是我们最终需要使用的progressDialog了。
public class CustomProgressDialog extends Dialog {
private Context context = null;
private static CustomProgressDialog customProgressDialog = null;
public CustomProgressDialog(Context context){
super(context);
this.context = context;
}
public CustomProgressDialog(Context context, int theme) {
super(context, theme);
}
public static CustomProgressDialog createDialog(Context context){
customProgressDialog = new CustomProgressDialog(context,R.style.CustomProgressDialog);
customProgressDialog.setContentView(R.layout.customprogressdialog);
customProgressDialog.getWindow().getAttributes().gravity = Gravity.CENTER;
return customProgressDialog;
}
public void onWindowFocusChanged(boolean hasFocus){
if (customProgressDialog == null){
return;
}
ImageView imageView = (ImageView) customProgressDialog.findViewById(R.id.loadingImageView);
AnimationDrawable animationDrawable = (AnimationDrawable) imageView.getBackground();
animationDrawable.start();
}
*
* [Summary]
* setTitile 标题
* @param strTitle
* @return
*
*/
public CustomProgressDialog setTitile(String strTitle){
return customProgressDialog;
}
/**
*
* [Summary]
* setMessage 提示内容
* @param strMessage
* @return
*
*/
public CustomProgressDialog setMessage(String strMessage){
TextView tvMsg = (TextView)customProgressDialog.findViewById(R.id.id_tv_loadingmsg);
if (tvMsg != null){
tvMsg.setText(strMessage);
}
return customProgressDialog;
}
}
没懂...
..其实我也没懂你的意思,你要设置那个颜色和背景,都是系统的,方法里只有设置标题和图标还有文字,要定义颜色和背景,要么重写这个,要么就自定义一个View放进去么
