android 自定义progressDialog实现
来源:互联网 发布:南京软件测试工资 编辑:程序博客网 时间:2024/06/06 02:06
我们在项目中经常会遇到这样一个应用场景:执行某个耗时操作时,为了安抚用户等待的烦躁心情我们一般会使用进度条之类的空间,在android中让大家最容易想到的就是progressbar或者progressDialog,区别在于前者是一个控件,后者是对话框。由于一些需求在弹出进度条时不希望用户能够操作其他控件,所以只能使用progressDialog,这个时候有遇到了一个问题,我不想要progressDialog的黑色框框,感觉这样跟应用的整体风格不协调,这个时候就考虑了写一个自定义的progressDialog。
在网上搜过很多自定义progressDialog的例子,对着写了下,但是没有任何效果,不知道是自己使用的方法不对还是什么地方出错了。通过不断的查找资料,写了一个简单的自定义progressDialog。先上图看下效果:
4.CustomProgressDialog.java文件,这个是就是我们最终需要使用的progressDialog了。
5.接下来就是写一个测试activity调用我们的progressDialog了。
在网上搜过很多自定义progressDialog的例子,对着写了下,但是没有任何效果,不知道是自己使用的方法不对还是什么地方出错了。通过不断的查找资料,写了一个简单的自定义progressDialog。先上图看下效果:
1.String.xml 文件,progressDialog是继承与Dialog,先设置一下progressDialog的风格,设置背景透明色。
- <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>
<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
- xmlns:android="http://schemas.android.com/apk/res/android"
- 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>
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 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
- xmlns:android="http://schemas.android.com/apk/res/android"
- 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>
<?xml version="1.0" encoding="utf-8"?><animation-listxmlns:android="http://schemas.android.com/apk/res/android" 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。

5.接下来就是写一个测试activity调用我们的progressDialog了。
- package com.lxd.activity;
- import com.lxd.widgets.CustomProgressDialog;
- import android.app.Activity;
- import android.os.AsyncTask;
- import android.os.Bundle;
- import android.view.Window;
- import android.view.WindowManager;
- public class MainFrame extends Activity {
- private MainFrameTask mMainFrameTask = null;
- private CustomProgressDialog progressDialog = null;
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- this.requestWindowFeature(Window.FEATURE_NO_TITLE);
- this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
- WindowManager.LayoutParams.FLAG_FULLSCREEN);
- setContentView(R.layout.main);
- mMainFrameTask = new MainFrameTask(this);
- mMainFrameTask.execute();
- }
- @Override
- protected void onDestroy() {
- stopProgressDialog();
- if (mMainFrameTask != null && !mMainFrameTask.isCancelled()){
- mMainFrameTask.cancel(true);
- }
- super.onDestroy();
- }
- private void startProgressDialog(){
- if (progressDialog == null){
- progressDialog = CustomProgressDialog.createDialog(this);
- progressDialog.setMessage("正在加载中...");
- }
- progressDialog.show();
- }
- private void stopProgressDialog(){
- if (progressDialog != null){
- progressDialog.dismiss();
- progressDialog = null;
- }
- }
- public class MainFrameTask extends AsyncTask<Integer, String, Integer>{
- private MainFrame mainFrame = null;
- public MainFrameTask(MainFrame mainFrame){
- this.mainFrame = mainFrame;
- }
- @Override
- protected void onCancelled() {
- stopProgressDialog();
- super.onCancelled();
- }
- @Override
- protected Integer doInBackground(Integer... params) {
- try {
- Thread.sleep(10 * 1000);
- } catch (InterruptedException e) {
- e.printStackTrace();
- }
- return null;
- }
- @Override
- protected void onPreExecute() {
- startProgressDialog();
- }
- @Override
- protected void onPostExecute(Integer result) {
- stopProgressDialog();
- }
- }
- }
package com.lxd.activity;import com.lxd.widgets.CustomProgressDialog;import android.app.Activity;import android.os.AsyncTask;import android.os.Bundle;import android.view.Window;import android.view.WindowManager;public class MainFrame extends Activity {private MainFrameTask mMainFrameTask = null;private CustomProgressDialog progressDialog = null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.requestWindowFeature(Window.FEATURE_NO_TITLE); this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.main); mMainFrameTask = new MainFrameTask(this); mMainFrameTask.execute(); } @Overrideprotected void onDestroy() {stopProgressDialog();if (mMainFrameTask != null && !mMainFrameTask.isCancelled()){mMainFrameTask.cancel(true);}super.onDestroy();}private void startProgressDialog(){if (progressDialog == null){progressDialog = CustomProgressDialog.createDialog(this); progressDialog.setMessage("正在加载中...");} progressDialog.show();}private void stopProgressDialog(){if (progressDialog != null){progressDialog.dismiss();progressDialog = null;}}public class MainFrameTask extends AsyncTask<Integer, String, Integer>{private MainFrame mainFrame = null;public MainFrameTask(MainFrame mainFrame){this.mainFrame = mainFrame;}@Overrideprotected void onCancelled() {stopProgressDialog();super.onCancelled();}@Overrideprotected Integer doInBackground(Integer... params) {try {Thread.sleep(10 * 1000);} catch (InterruptedException e) {e.printStackTrace();}return null;}@Overrideprotected void onPreExecute() {startProgressDialog();}@Overrideprotected void onPostExecute(Integer result) {stopProgressDialog();}}}
这样我们需要的progressDialog效果就出来了,希望对遇到跟我类似问题的朋友有所帮助,里面有什么写的不对的地方请大家指教。
