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

---

配置

style.xml中配置

<style name="BoxDialog" parent="@android:style/Theme.Holo.Dialog">
    
    "android:windowFrame">@null
    
    "android:windowIsFloating">true
    
    "android:windowNoTitle">true
    
    "android:windowIsTranslucent">true
    
    "android:windowBackground">@android:color/transparent
    
style>

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()
        }
    }
