### 一、在layout下创建布局 dialog\_help.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:background="@drawable/bg_round_white"
        android:orientation="vertical" >
    
        <TextView
            android:id="@+id/failure_title"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center_horizontal"
            android:padding="@dimen/dp_12"
            android:layout_marginTop="@dimen/top"
            android:textSize="@dimen/text_size_b"
            android:textColor="@color/colorTextHint"/>
    
        <TextView
            android:id="@+id/failure_content"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:layout_gravity="center_horizontal"
            android:lineSpacingExtra="@dimen/dp_3"
            android:layout_marginLeft="@dimen/dp_20"
    
            android:layout_marginRight="@dimen/dp_20"
            android:layout_marginBottom="@dimen/dp_20"
            android:textSize="@dimen/text_size"
            android:textColor="@color/colorTextHint"/>
        <View
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:background="@color/colorBackGround"/>
    
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="@dimen/info_height"
            android:orientation="horizontal">
    
            <TextView
                android:id="@+id/failure_back"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="@drawable/bg_dialog_left_white"
                android:layout_weight="1.0"
                android:gravity="center"
                android:text="返回"
                android:textSize="@dimen/text_size"
                android:textColor="@color/colorBlue"/>
    
            <View
                android:layout_width="1dp"
                android:layout_height="match_parent"
                android:background="@color/colorBackGround"/>
    
            <TextView
                android:id="@+id/failure_ok"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="@drawable/bg_dialog_right_white"
                android:gravity="center"
                android:layout_weight="1.0"
                android:text="帮助"
                android:textSize="@dimen/text_size"
                android:textColor="@color/colorBlue"/>
    
        </LinearLayout>
    
    </LinearLayout>

### 二、在drawable下创建 ###

**bg\_round\_white.xml**

<?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
        <solid android:color="@color/colorWhite" />
        <corners android:radius="@dimen/dp_8" />
    </shape>

**bg\_dialog\_left\_white.xml**

**bg\_dialog\_right\_white.xml**

三、新建CommomDialog类 代码

package com.xinli.wenet.views;
    
    import android.app.Dialog;
    import android.content.Context;
    import android.os.Bundle;
    import android.text.TextUtils;
    import android.view.Gravity;
    import android.view.View;
    import android.view.Window;
    import android.widget.TextView;
    
    import com.xinli.wenet.R;
    
    
    /**
     * The type Commom dialog.
     */
    public class CommomDialog extends Dialog implements View.OnClickListener{
        private TextView contentTxt;
        private TextView titleTxt;
        private TextView submitTxt;
        private TextView cancelTxt;
    
        private Context mContext;
        private String content;
        private OnCloseListener listener;
        private String positiveName;
        private String negativeName;
        private String title;
    
        /**
         * Instantiates a new Commom dialog.
         *
         * @param context the context
         */
        public CommomDialog(Context context) {
            super(context);
            this.mContext = context;
        }
    
        /**
         * Instantiates a new Commom dialog.
         *
         * @param context    the context
         * @param themeResId the theme res id
         * @param content    the content
         */
        public CommomDialog(Context context, int themeResId, String content) {
            super(context, themeResId);
            this.mContext = context;
            this.content = content;
        }
    
        /**
         * Instantiates a new Commom dialog.
         *
         * @param context    the context
         * @param themeResId the theme res id
         * @param content    the content
         * @param listener   the listener
         */
        public CommomDialog(Context context, int themeResId, String content, OnCloseListener listener) {
            super(context, themeResId);
            this.mContext = context;
            this.content = content;
            this.listener = listener;
        }
    
        /**
         * Instantiates a new Commom dialog.
         *
         * @param context        the context
         * @param cancelable     the cancelable
         * @param cancelListener the cancel listener
         */
        protected CommomDialog(Context context, boolean cancelable, OnCancelListener cancelListener) {
            super(context, cancelable, cancelListener);
            this.mContext = context;
        }
    
        /**
         * Set title commom dialog.
         *
         * @param title the title
         * @return the commom dialog
         */
        public CommomDialog setTitle(String title){
            this.title = title;
            return this;
        }
    
        /**
         * Set positive button commom dialog.
         *
         * @param name the name
         * @return the commom dialog
         */
        public CommomDialog setPositiveButton(String name){
            this.positiveName = name;
            return this;
        }
    
        /**
         * Set negative button commom dialog.
         *
         * @param name the name
         * @return the commom dialog
         */
        public CommomDialog setNegativeButton(String name){
            this.negativeName = name;
            return this;
        }
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.dialog_help);
            setCanceledOnTouchOutside(false);
            Window window = getWindow();
            assert window != null;
            window.setGravity(Gravity.CENTER);  //此处可以设置dialog显示的位置
           // window.setWindowAnimations(R.style.mystyle);  //添加动画
            initView();
        }
    
        private void initView(){
            contentTxt = (TextView)findViewById(R.id.failure_content);
            titleTxt = (TextView)findViewById(R.id.failure_title);
            submitTxt = (TextView)findViewById(R.id.failure_ok);
            submitTxt.setOnClickListener(this);
            cancelTxt = (TextView)findViewById(R.id.failure_back);
            cancelTxt.setOnClickListener(this);
    
            contentTxt.setText(content);
            if(!TextUtils.isEmpty(positiveName)){
                submitTxt.setText(positiveName);
            }
    
            if(!TextUtils.isEmpty(negativeName)){
                cancelTxt.setText(negativeName);
            }
    
            if(!TextUtils.isEmpty(title)){
                titleTxt.setText(title);
            }
    
        }
    
        @Override
        public void onClick(View v) {
            switch (v.getId()){
                case R.id.failure_back:
                    if(listener != null){
                        listener.onClick(this, false);
                    }
                    this.dismiss();
                    break;
                case R.id.failure_ok:
                    if(listener != null){
                        listener.onClick(this, true);
                    }
                    break;
            }
        }
    
        /**
         * The interface On close listener.
         */
        public interface OnCloseListener{
            /**
             * On click.
             *
             * @param dialog  the dialog
             * @param confirm the confirm
             */
            void onClick(Dialog dialog, boolean confirm);
        }
    }

### 四、在新values下建样式 ###

### 五、使用 ###

new CommomDialog(this, R.style.dialogs, "数据清除不可恢复,确定要清除数据吗?", new CommomDialog.OnCloseListener() {
                        @Override
                        public void onClick(Dialog dialog, boolean confirm) {
                            if (confirm) {
                                dialog.dismiss();
                 
                          }
    
                        }
                    }).setTitle("清除数据提示").setPositiveButton("确定").show();

结束...
