loadingDialog

1.dialog布局 dialog_loading.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/dialog_view"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/bg"
    android:gravity="center"
    android:minHeight="60dp"
    android:minWidth="180dp"
    android:orientation="vertical"
    android:padding="10dp" >

    <ImageView
        android:id="@+id/img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/base_loading_large_icon" />
<!--  
    <TextView
        android:gravity="center"
        android:id="@+id/tipTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp" />
-->
</LinearLayout>

2.图像的旋转动画 loading_animation.xml

<?xml version="1.0" encoding="utf-8"?>
<set android:shareInterpolator="false" xmlns:android="http://schemas.android.com/apk/res/android">
    <rotate 
        android:interpolator="@android:anim/linear_interpolator"
        android:pivotX="50%"
        android:pivotY="50%"
        android:fromDegrees="0"
        android:toDegrees="+360"
        android:duration="1500"
        android:startOffset="-1"
        android:repeatMode="restart"
        android:repeatCount="-1"/>
</set>

3.dialog的style

 <!-- 自定义loading dialog -->
    <style name="loading_dialog" parent="android:style/Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
    </style>

4.dialog类

package com.jingle.progressdialog;

import android.annotation.SuppressLint;
import android.app.Dialog;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.ImageView;
import android.widget.LinearLayout;

@SuppressLint("InflateParams")
public class LoadingDialog {

    private LoadingDialog() {

    }

    private static Dialog mLoadingDialog = null;

    // 单例模式
    public static Dialog getLoadingDialog(Context context, String msg) {

        LayoutInflater inflater = LayoutInflater.from(context);
        View v = inflater.inflate(R.layout.dialog_loading, null);// 得到加载对话框的view
        LinearLayout layout = (LinearLayout) v.findViewById(R.id.dialog_view);// 加载对话框布局

        ImageView spaceshipImage = (ImageView) v.findViewById(R.id.img);// 加载的图像
        // TextView tipTextView = (TextView) v.findViewById(R.id.tipTextView);//
        // 提示文字
        // tipTextView.setText(msg);// 设置加载信息
        // 加载动画
        Animation hyperspaceJumpAnimation = AnimationUtils.loadAnimation(
                context, R.anim.loading_animation);
        // 使用ImageView显示动画
        spaceshipImage.startAnimation(hyperspaceJumpAnimation);

        if (mLoadingDialog == null) {
            mLoadingDialog = new Dialog(context, R.style.loading_dialog0);
        }

        // Dialog loadingDialog = new Dialog(context, R.style.loading_dialog);//
        // 创建自定义样式dialog

        // loadingDialog.setCancelable(false);// 不可以用“返回键”取消
        mLoadingDialog.setContentView(layout, new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.MATCH_PARENT,
                LinearLayout.LayoutParams.MATCH_PARENT));// 设置布局
        return mLoadingDialog;

    }
}

 

5.调用dialogMainActivity.java

package com.jingle.progressdialog;

import java.util.Timer;
import java.util.TimerTask;

import android.app.Activity;
import android.app.Dialog;
import android.os.Bundle;

public class MainActivity extends Activity {
    private Dialog dialog = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        initDialog();
    }

    private void initDialog() {
        dialog = LoadingDialog.getLoadingDialog(this, "");
        dialog.show();
        Timer timer = new Timer();
        timer.schedule(new Task(), 3000);
    }
    
    class Task extends TimerTask {
        public void run() {
            dialog.dismiss();//解散dialog
        }        
    }

}
