Android自定义进度条主要是修改ProgressBar的style,弹窗则是在Dialog里显示ProgressBar。
直接上代码。
在style.xml里加入如下代码:
[html]
<style name="ProgressBar_Mini" parent="@android:style/Widget.ProgressBar.Horizontal">
<item name="android:maxHeight">50dip</item>
<item name="android:minHeight">8dip</item>
<item name="android:indeterminateOnly">false</item>
<item name="android:indeterminateDrawable">@android:drawable/progress_indeterminate_horizontal</item>
<item name="android:progressDrawable">@drawable/progressbar_mini</item>
</style>
新建drawable/progressbar_mini.xml内容如下:
[html]
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="@android:id/background">
<shape>
<corners android:radius="0dip" />
<gradient
android:angle="270"
android:centerY="0.75"
android:endColor="#F5F5F5"
android:startColor="#BEBEBE" />
</shape>
</item>
<item android:id="@android:id/secondaryProgress">
<clip>
<shape>
<corners android:radius="0dip" />
<gradient
android:angle="270"
android:centerY="0.75"
android:endColor="#165CBC"
android:startColor="#85B0E9" />
</shape>
</clip>
</item>
<item android:id="@android:id/progress">
<clip>
<shape>
<corners android:radius="0dip" />
<gradient
android:angle="270"
android:centerY="0.75"
android:endColor="#00FF66"
android:startColor="#00FF66" />
</shape>
</clip>
</item>
</layer-list>
myprogressbar.xml的内容如下:
[html]
<?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:background="@drawable/back_qian"
android:gravity="center"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="正在切换状态...."
android:textSize="18sp"
android:textColor="@color/black" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="" />
<ProgressBar
android:id="@+id/progressBar1"
style="@style/ProgressBar_Mini"
android:layout_width="290dp"
android:layout_height="17dp" />
</LinearLayout>
MyProgressBar.java的内容如下:
[java]
package com.wl.util;
import android.app.Dialog;
import android.content.Context;
import android.content.DialogInte易做图ce;
import android.content.DialogInte易做图ce.OnCancelListener;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ProgressBar;
import com.wl.R;
public class MyProgressBar {
Dialog dialog;
Context context;
// 声明ProgressBar对象
private ProgressBar pro1;
/**
* 构造
*/
public MyProgressBar(Context context) {
// TODO Auto-generated constructor stub
this.context = context;
dialog = new Dialog(context, R.style.dialog);
dialog.setOnCancelListener(onCancelListener);
}
