自定义ProgressDialog

今天在项目中用到了ProgressDialog,但是项目组长觉得样子有点丑,需要改写一下样式,于是就自定义了一个ProgressDialog,下面详细介绍下过程

效果图

首先打开AndroidSudio新建一个项目

MainActivity里面只有一个Button,作为点击按钮使用,点击之后就会显示我们要自定义的ProgressDialog

为Button添加点击事件

package com.example.hfs.customprogressdialog;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.widget.Button;public class MainActivity extends AppCompatActivity {    private Button mButton;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initView();    }    private void initView() {        mButton= (Button) this.findViewById(R.id.btn_test);        mButton.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {            }        });    }}

下面就是开始自定义我们的控件了

首先写下我们要用的的Style

<resources>    <!-- Base application theme. -->    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">        <!-- Customize your theme here. -->        <item name="colorPrimary">@color/colorPrimary</item>        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>        <item name="colorAccent">@color/colorAccent</item>    </style>    <!--自定义的Style-->    <style name="common_dialog" parent="@android:style/Theme.Dialog">        <item name="android:windowIsFloating">true</item>        <!-- 设置未浮动窗口 -->        <item name="android:windowFrame">@null</item>        <!-- 设置无边框 -->        <item name="android:windowNoTitle">true</item>        <!-- 设置无标题 -->        <item name="android:windowBackground">@android:color/transparent</item>        <!-- 设置完全透明 -->        <item name="android:backgroundDimEnabled">false</item>        <!-- 设置屏幕变暗 -->    </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></resources>

然后是布局XML

<?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="@drawable/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>

接下来就是最主要的代码了

package com.example.hfs.customprogressdialog;import android.app.Dialog;import android.content.Context;import android.graphics.drawable.AnimationDrawable;import android.view.Gravity;import android.widget.ImageView;import android.widget.TextView;/** * Created by HFS on 2016/7/5. */public class CustomDialog extends Dialog {    private Context context = null;    private static CustomDialog customProgressDialog = null;    public CustomDialog(Context context) {        super(context);        this.context = context;    }    public CustomDialog(Context context, int theme) {        super(context, theme);    }    public static CustomDialog createDialog(Context context) {        customProgressDialog = new CustomDialog(context,                R.style.CustomProgressDialog);        customProgressDialog.setCanceledOnTouchOutside(false);        customProgressDialog.setContentView(R.layout.customprogressdialog);        customProgressDialog.getWindow().getAttributes().gravity = Gravity.CENTER;        return customProgressDialog;    }    public void onWindowFocusChanged(boolean hasFocus) {        if (customProgressDialog == null) {            return;        }        ImageView imageView = (ImageView) customProgressDialog                .findViewById(R.id.loadingImageView);        AnimationDrawable animationDrawable = (AnimationDrawable) imageView                .getBackground();        animationDrawable.start();    }    public CustomDialog setTitile(String strTitle) {        return customProgressDialog;    }    public CustomDialog setMessage(String strMessage) {        TextView tvMsg = (TextView) customProgressDialog.findViewById(R.id.id_tv_loadingmsg);        if (tvMsg != null) {            tvMsg.setText(strMessage);        }        return customProgressDialog;    }}

在MainActivity中写两个方法启动Dialog和停止Dialog

    private void stopProgressDialog() {        if (mCustomDialog != null) {            mCustomDialog.dismiss();            mCustomDialog = null;        }    }    private void startProgressDialog() {        if (mCustomDialog == null) {            mCustomDialog = CustomDialog.createDialog(this);            mCustomDialog.setMessage("正在加载中...");        }        mCustomDialog.show();    }

在MainActivity中的Button点击事件中start 2秒中后发送一个通知,stop

   package com.example.hfs.customprogressdialog;import android.os.Handler;import android.os.Message;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.widget.Button;public class MainActivity extends AppCompatActivity {    private Button mButton;    private CustomDialog mCustomDialog;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initView();    }    private void initView() {        mButton = (Button) this.findViewById(R.id.btn_test);        mButton.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                startProgressDialog();                mHandler.sendEmptyMessageDelayed(0, 2000);            }        });    }    private Handler mHandler = new Handler() {        @Override        public void handleMessage(Message msg) {            super.handleMessage(msg);            stopProgressDialog();        }    };    private void startProgressDialog() {        if (mCustomDialog == null) {            mCustomDialog = CustomDialog.createDialog(this);            mCustomDialog.setMessage("正在加载中...");        }        mCustomDialog.show();    }    private void stopProgressDialog() {        if (mCustomDialog != null) {            mCustomDialog.dismiss();            mCustomDialog = null;        }    }}

OK这样一个简单的自定义ProgressDialog就完成了
