Android 安卓自定义Dialog工具类封装与使用

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"> <!-- 是否有边框 --> <item name="android:windowFrame">@null</item> <!--是否在悬浮Activity之上  --> <item name="android:windowIsFloating">true</item> <!-- 标题 --> <item name="android:windowNoTitle">true</item> <!--阴影  --> <item name="android:windowIsTranslucent">true</item> <!--背景透明--> <item name="android:windowBackground">@android:color/transparent</item> <!--可加入动画-->
</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(); } }); }

}
