1、自定义dialog:引入样式和代码指定样式
package com.gxjl.pe.gxjlpesdk.view; import android.app.Dialog; import android.content.Context; import android.os.Bundle; import android.support.annotation.NonNull; import android.support.annotation.Nullable; import android.util.DisplayMetrics; import android.view.Gravity; import android.view.View; import android.view.Window; import android.view.WindowManager; import android.widget.TextView; import com.gxjl.pe.gxjlpesdk.R; /** * 相机、相册选择 弹框 * Created by xiaoshuai on 2018/8/20. */ public abstract class CameraPhotoDialog extends Dialog implements View.OnClickListener{ private Context context; public CameraPhotoDialog(@NonNull Context context) { super(context, R.style.dialogTransparent);//内容样式在这里引入 this.context = context; } public CameraPhotoDialog(@NonNull Context context, int themeResId) { super(context, themeResId); } protected CameraPhotoDialog(@NonNull Context context, boolean cancelable, @Nullable OnCancelListener cancelListener) { super(context, cancelable, cancelListener); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.dialog_camrea_photo); //tv_title = findViewById(R.id.tv_title); Window dialogWindow = getWindow(); WindowManager.LayoutParams lp = dialogWindow.getAttributes(); DisplayMetrics d = context.getResources().getDisplayMetrics(); // 获取屏幕宽、高用 lp.width = (int) (d.widthPixels * 0.9); // 宽度设置为屏幕宽度的80% //lp.dimAmount=0.0f;//外围遮罩透明度0.0f-1.0f dialogWindow.setAttributes(lp); dialogWindow.setGravity(Gravity.BOTTOM);//内围区域底部显示 } @Override public void onClick(View view) { int i = view.getId(); if (i == R.id.tv_cancel) { this.dismiss(); } } protected abstract void confirm(); }
2、dialog_camrea_photo.xml 布局
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@android:color/transparent" android:orientation="vertical"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginBottom="10dp" android:background="@android:color/transparent" android:orientation="vertical"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@drawable/bg_camera_check" android:orientation="vertical"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="15dp" android:layout_gravity="center_horizontal" android:text="拍照" android:textSize="16sp" android:textColor="@color/font_007AFF"/> <View android:layout_width="match_parent" android:layout_height="1dp" android:background="@color/line_ECECED"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="15dp" android:layout_gravity="center_horizontal" android:text="照片图库" android:textSize="16sp" android:textColor="@color/font_007AFF"/> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="10dp" android:background="@drawable/bg_camera_check" android:orientation="vertical"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="15dp" android:layout_gravity="center_horizontal" android:text="拍照" android:textSize="16sp" android:textColor="@color/font_007AFF"/> </LinearLayout> </LinearLayout> </LinearLayout>
3、style.xml 样式布局:指定dialog内容样式
<?xml version="1.0" encoding="utf-8"?> <resources> <style name="dialogTransparent" parent="@android:style/Theme.Dialog"> <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:background">@android:color/transparent</item> <!--背景透明--> <item name="android:windowBackground">@android:color/transparent</item> <!--背景透明--> <item name="android:backgroundDimEnabled">true</item> <!--模糊--> <item name="android:backgroundDimAmount">0.6</item> <!--背景透明度--> </style> </resources>
