自定义ProgressDialog（无遮罩效果）

1.自定义progressDialog的theme：

    <!-- 自定义Dialog -->    <style name="Custom_Progress" parent="@android:style/Theme.Dialog">        <!-- 无边框 -->        <item name="android:windowFrame">@null</item>        <!-- 是否浮现在activity之上 -->        <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>        <item name="android:windowBackground">@android:color/transparent</item>        <item name="android:windowNoTitle">true</item>        <!--无遮罩效果-->        <item name="android:backgroundDimEnabled">false</item>    </style>

2.自定义的CustomProgressDialog extends Dialog：

package com.ylj.progressdialogdemo;import android.app.Dialog;import android.content.Context;import android.view.Gravity;import android.view.View;import android.view.WindowManager;import android.widget.TextView;  public class CustomProgressDialog extends Dialog {  private static CustomProgressDialog dialog;public CustomProgressDialog(Context context) {          super(context);      }        public CustomProgressDialog(Context context, int theme) {          super(context, theme);      }            /**      * 弹出自定义ProgressDialog      *       * @param context      *            上下文      * @param message      *            提示      * @param cancelable      *            是否可取消      * @param cancelListener      *            按下返回键监听      * @return      */      public static CustomProgressDialog show(Context context, CharSequence message, boolean cancelable, OnCancelListener cancelListener) {     if(dialog == null){    dialog = new CustomProgressDialog(context, R.style.Custom_Progress);      }        dialog.setTitle("");          dialog.setContentView(R.layout.layout_progress_dialog);                  if (message == null || message.length() == 0) {              dialog.findViewById(R.id.tv_message).setVisibility(View.GONE);          } else {              TextView tv_message = (TextView) dialog.findViewById(R.id.tv_message);              tv_message.setText(message);          }          // 按返回键是否取消          dialog.setCancelable(cancelable);          // 监听返回键处理          dialog.setOnCancelListener(cancelListener);          // 设置居中          dialog.getWindow().getAttributes().gravity = Gravity.CENTER;          WindowManager.LayoutParams lp = dialog.getWindow().getAttributes();          // 设置背景层透明度          lp.dimAmount = 0.1f;          dialog.getWindow().setAttributes(lp);          dialog.show();                  return dialog;      }         /**     * 关闭dialog     */    public static void dimiss() {          if(dialog != null && dialog.isShowing()){        dialog.dismiss();        }    }}

3.layout_progress_dialog.xml 布局：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:layout_gravity="center"    android:background="@drawable/progress_custom_bg"    android:gravity="center_horizontal"    android:orientation="vertical"    android:paddingBottom="20dp"    android:paddingLeft="25dp"    android:paddingRight="25dp"    android:paddingTop="20dp" >    <ProgressBar        android:id="@+id/pb"        android:layout_width="40dp"        android:layout_height="40dp"        android:layout_gravity="center_horizontal" />    <TextView        android:id="@+id/tv_message"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center_vertical"        android:layout_marginTop="3dp"        android:textSize="16sp" /></LinearLayout>

4.MainActivity：

package com.ylj.progressdialogdemo;import android.app.Activity;import android.os.AsyncTask;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;public class MainActivity extends Activity implements OnClickListener {@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);findViewById(R.id.btn_save).setOnClickListener(this);}@Overridepublic void onClick(View v) {new LoginTask().execute();}private class LoginTask extends AsyncTask<Void, Void, Void> {@Overrideprotected void onPreExecute() {CustomProgressDialog.show(MainActivity.this, "登录中...", false, null);super.onPreExecute();}@Overrideprotected Void doInBackground(Void... params) {try {new Thread().sleep(2000);} catch (InterruptedException e) {e.printStackTrace();}return null;}@Overrideprotected void onPostExecute(Void result) {super.onPostExecute(result);CustomProgressDialog.dimiss();}}}

5.activity_main.xml布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="com.ylj.progressdialogdemo.MainActivity" >    <Button        android:id="@+id/btn_save"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_centerInParent="true"        android:text="登录" /></RelativeLayout>
