本文介绍最常用的四种对话框的使用方法，包括普通（包含提示消息和按钮）对话框、列表展示对话框、加载对话框、编辑对话框等多种形式。

一、前期准备

1. 设置对话框背景 dialog_bg_normal.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <corners android:radius="10dp"/>
    <solid android:color="@color/white"/>
    <stroke android:color="#cbcbcb" android:width="1px"/>
</shape>

2. 设置风格

<style name="customDialog" parent="@android:style/Theme.Dialog">
        <!--dialog的背景，此处是一个圆角白底的xml文件，也可以是.9图-->
        <item name="android:windowBackground">@drawable/dialog_bg_normal</item>
        <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
        <item name="android:windowFrame">@null</item><!--边框-->
        <item name="android:windowIsFloating">true</item><!--是否浮现在activity之上-->
        <item name="android:windowIsTranslucent">true</item><!--半透明-->
        <item name="android:windowNoTitle">true</item><!--无标题-->
        <item name="android:backgroundDimEnabled">true</item><!--模糊-->
    </style>

3. 自定义对话框

public class CommonDialog extends Dialog {
    private Window mWindow;

    public CommonDialog(@NonNull Context context) {
        super(context);
    }

    public CommonDialog(@NonNull Context context, int themeResId) {
        super(context, themeResId);
    }

    protected CommonDialog(@NonNull Context context, boolean cancelable, @Nullable OnCancelListener cancelListener) {
        super(context, cancelable, cancelListener);
    }

    public void setView(View view) {
        setContentView(view);
    }

    public void setView(int ID) {
        setContentView(ID);
    }

    public void setProperty(int x,int y,int w,int h) {
        mWindow = getWindow();
        WindowManager.LayoutParams params = mWindow.getAttributes();
        params.x = x;  //设置对话框的位置，0为中间
        params.y = y;
        params.width = w;
        params.height = h;
        params.alpha = 1.0f; //设置对话框的透明度,1f不透明
        params.gravity = Gravity.CENTER; //设置显示在中间
        mWindow.setAttributes(params);
    }
}

二、普通（包含提示消息和按钮）对话框

1. 效果图

2. 布局文件 dialog_device_add_notice.xml

3. 逻辑代码

private CommonDialog mDialog;
  public void click(View view) {
        showDialog();
    }

    private void showDialog() {
        mDialog = new CommonDialog(this,R.style.customDialog);
        View view = View.inflate(this, R.layout.dialog_device_add_notice,null);
        final LinearLayout llBefore = (LinearLayout)view.findViewById(R.id.ll_before);
        final LinearLayout llAfter = (LinearLayout)view.findViewById(R.id.ll_after);
        final ImageView imgWaiting = (ImageView) view.findViewById(R.id.img_config_icon1);
        TextView txtTitle = (TextView) view.findViewById(R.id.txt_title);
        txtTitle.setText(getString(R.string.base_update_notice));
        final TextView txtMsg = (TextView) view.findViewById(R.id.txt_msg);
        TextView txtCancle = (TextView) view.findViewById(R.id.txt_cancle);
        txtMsg.setText(getString(R.string.base_need_update));
        txtMsg.setGravity(Gravity.CENTER);
        txtCancle.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mDialog.dismiss();
            }
        });
        TextView txtOk = (TextView) view.findViewById(R.id.txt_ok);
        llBefore.setVisibility(View.VISIBLE);
        llAfter.setVisibility(View.GONE);
        txtOk.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //versionDialog.dismiss();
                //updateVersion();
                txtMsg.setText("正在搜索，请稍后...");
                llBefore.setVisibility(View.GONE);
                llAfter.setVisibility(View.VISIBLE);

                AnimationDrawable animationDrawable = (AnimationDrawable) imgWaiting.getDrawable();
                if(animationDrawable != null){
                    animationDrawable.start();
                }
            }
        });
        mDialog.setView(view);
        mDialog.setProperty(0,0,800,600);
        mDialog.setCanceledOnTouchOutside(true);
        mDialog.show();
    }

三、列表对话框

1. 布局文件 dialog_delete_edit.xml

<?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:orientation="vertical">

    <TextView
        android:id="@+id/txt_use"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:padding="@dimen/DIMEN_15dp"
        android:text="使用场景"
        android:textColor="@color/base_normal_txt_title"
        android:textSize="@dimen/DIMEN_15sp" />

    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="@color/bg_detail"></View>

    <TextView
        android:id="@+id/txt_edit"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:padding="@dimen/DIMEN_15dp"
        android:text="编辑场景"
        android:textColor="@color/base_normal_txt_title"
        android:textSize="@dimen/DIMEN_15sp" />

    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="@color/bg_detail"></View>

    <TextView
        android:id="@+id/txt_delete"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:padding="@dimen/DIMEN_15dp"
        android:text="删除场景"
        android:textColor="@color/base_normal_txt_title"
        android:textSize="@dimen/DIMEN_15sp" />
</LinearLayout>

2. 逻辑代码

public void show2(View view) {
        show();
    }

    private void show(){
        mSelectDialog = new CommonDialog(this,R.style.customDialog);
        View view = View.inflate(this,R.layout.dialog_delete_edit,null);
        TextView txtUse = (TextView) view.findViewById(R.id.txt_use);
        TextView txtEdit = (TextView) view.findViewById(R.id.txt_edit);
        TextView txtDelete = (TextView) view.findViewById(R.id.txt_delete);
        txtUse.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mSelectDialog.dismiss();

            }
        });
        txtEdit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mSelectDialog.dismiss();

            }
        });
        txtDelete.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mSelectDialog.dismiss();

            }
        });

        mSelectDialog.setView(view);
        mSelectDialog.setProperty(0,0,800,420);
        mSelectDialog.setCanceledOnTouchOutside(true);
        mSelectDialog.show();
    }

四、加载对话框

1. 布局文件dialog_device_add_notice.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

            android:textSize="@dimen/DIMEN_15sp" />
    </LinearLayout>
</RelativeLayout>

2. 逻辑代码

private CommonDialog mDialog;
  public void click(View view) {
        showDialog();
    }

    private void showDialog() {
        mDialog = new CommonDialog(this,R.style.customDialog);

        txtOk.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
