代码

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>
