这篇文章主要为大家详细介绍了Android实现弹窗进度条效果,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
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:
<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>
<style name="dialog" parent="@android:style/Theme.Dialog">
<item name="android:windowFrame">@null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowNoTitle">true</item>
<item name="android:backgroundDimEnabled">true</item>
<item name="android:windowBackground">@color/transparent</item>
</style>
新建drawable/progressbar_mini.xml内容如下:
<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">
<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">
<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:
<?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:
package com.wl.util;
import android.app.Dialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.DialogInterface.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;
public MyProgressBar(Context context) {
// TODO Auto-generated constructor stub
this.context = context;
dialog = new Dialog(context, R.style.dialog);
dialog.setOnCancelListener(onCancelListener);
* 初始化进度对话框
public void initDialog() {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.myprogressbar, null);
dialog.setContentView(view);
pro1 = (ProgressBar) dialog.findViewById(R.id.progressBar1);
// 设置进度条是否自动旋转,即设置其不确定模式,false表示不自动旋转
pro1.setIndeterminate(false);
// 设置ProgressBar的最大值
pro1.setMax(100);
// 设置ProgressBar的当前值
pro1.setProgress(0);
dialog.show();
public void setProgress(int progressValue) {
pro1.setProgress(progressValue);
public void colseDialog() {
dialog.dismiss();
public boolean isShowing() {
if (dialog.isShowing()) {
return true;
} else {
return false;
OnCancelListener onCancelListener = new OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
// TODO Auto-generated method stub
dialog.dismiss();
调用代码如下:
MyProgressBar myProgressBar;
myProgressBar = new MyProgressBar(Dialog_TestActivity.this);
myProgressBar.initDialog();
new Thread(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
try {
Thread.sleep(200);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
for (int i = 0; i < 100; i++) {
handler.sendEmptyMessage(0);
try {
Thread.sleep(30);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}).start();
Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
// 改变ProgressBar的当前值
myProgressBar.setProgress(intCounter++);
if (intCounter == 100) {
intCounter = 0;
myProgressBar.colseDialog();
按返回退出:
@Override
public void onBackPressed() {
// TODO Auto-generated method stub
Log.d("11", "onBackPressed()");
if (myProgressDialog.isShowing()) {
myProgressDialog.colseDialog();
if (myProgressBar.isShowing()) {
myProgressBar.colseDialog();
super.onBackPressed();
