## Android 安卓Dialog工具类封装与使用 ##

安卓自定义Dialog，分别用了Kotlin和Java两种语言列出！布局可以自定义！

--------------------

### 效果图 ###

布局是自定义的

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwODgxNjgw_size_16_color_FFFFFF_t_70_pic_center]

--------------------

### 配置 ###

style.xml中配置

--------------------

### Java ###

### Kotlin ###

/** * @author ThirdGoddess * @email ofmyhub@gmail.com * @Github https://github.com/ThirdGoddess * @date :2019-12-29 01:24 */
    class BoxDialog : Dialog { 
    
        //Dialog View
        private var view: View?
    
        //Dialog弹出位置
        private var locationView = LocationView.CENTER
    
        /** * @param context 上下文 * @param view Dialog View */
        constructor(context: Context?, view: View?) : super(context!!, R.style.MyDialog) { 
            this.view = view
        }
    
        /** * @param context 上下文 * @param view Dialog View * @param locationView Dialog弹出位置 */
        constructor(context: Context?, view: View?, locationView: LocationView) : super(context!!, R.style.MyDialog) { 
            this.view = view
            this.locationView = locationView
        }
    
        @SuppressLint("RtlHardcoded")
        override fun onCreate(savedInstanceState: Bundle) { 
            super.onCreate(savedInstanceState)
            if (null != view) { 
                setContentView(view!!)
                setCancelable(isCancelable) //点击外部是否可以关闭Dialog
                setCanceledOnTouchOutside(isCanceledOnTouchOutside) //返回键是否可以关闭Dialog
                val window = this.window!!
                when (locationView) { 
                    LocationView.TOP -> window.setGravity(Gravity.TOP)
                    LocationView.BOTTOM -> window.setGravity(Gravity.BOTTOM)
                    LocationView.CENTER -> window.setGravity(Gravity.CENTER)

        }
    
        enum class LocationView { 
            CENTER, TOP, BOTTOM
        }
    }

## 使用方法 ##

Java 和 Kotlin 的方法

--------------------

### Java ###

public class MainActivity extends AppCompatActivity { 
        
        private BoxDialog boxDialog;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) { 
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            initView();
        }
    
        private void initView() { 
            Button dialogButton = findViewById(R.id.dialog);
            dialogButton.setOnClickListener(new View.OnClickListener() { 
                @Override
                public void onClick(View v) { 
                    View inflate = LayoutInflater.from(MainActivity.this).inflate(R.layout.dialog_view2, null, false);
                    //在这里可以给布局中的按钮加事件，boxDialog.dismiss()可以关闭dialog
    
                    boxDialog = new BoxDialog(MainActivity.this, inflate, BoxDialog.LocationView.CENTER);
                    boxDialog.setCancelable(false);//是否可以点击DialogView外关闭Dialog
                    boxDialog.setCanceledOnTouchOutside(false);//是否可以按返回按钮关闭Dialog
                    boxDialog.show();
                }
            });
        }
    
    }

--------------------

### Kotlin ###

class MainActivity : AppCompatActivity() { 
        private var boxDialog: BoxDialog? = null
        override fun onCreate(savedInstanceState: Bundle?) { 
            super.onCreate(savedInstanceState)
            setContentView(R.layout.activity_main)
            initView()
        }
    
        private fun initView() { 
            val dialogButton = findViewById<Button>(R.id.dialog)
            dialogButton.setOnClickListener { 
                val inflate = LayoutInflater.from(this).inflate(R.layout.dialog_view2, null, false)
                //可以给布局中的按钮加事件，boxDialog.dismiss();关闭dialog
                
                boxDialog = BoxDialog(this, inflate, BoxDialog.LocationView.CENTER)
                boxDialog!!.setCancelable(false) //是否可以点击DialogView外关闭Dialog
                boxDialog!!.setCanceledOnTouchOutside(false) //是否可以按返回按钮关闭Dialog
                boxDialog!!.show()
            }
        }
    }
