标准 看完这个帖子一定看看这个， 两个结合 ， 实现  拍照 相册 回调

https://blog.csdn.net/bbtianshi/article/details/81223777

主页面布局  这里对应的就是一个点击事件 实现 ，

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@color/gray"
    tools:context="com.lbb.rosewood.mine.view.activity.CameraActivity">
<Button
    android:id="@+id/dianji"
    android:text="测试"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />
</LinearLayout>

第二步对应 在创建 底部弹出框的布局

<?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:orientation="vertical"
    android:background="@color/gray"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/camera"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:padding="@dimen/margin15"
        android:text="拍照"
        android:textColor="@color/bottom_blue"
        android:textSize="@dimen/textsize20"
        tools:ignore="HardcodedText,RtlHardcoded" />

    <View
        android:layout_width="match_parent"
        android:layout_height="@dimen/line_1"
        android:background="@color/error_bg" />

    <TextView
        android:id="@+id/pic"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:padding="@dimen/margin15"
        android:text="相册"
        android:textColor="@color/bottom_blue"
        android:textSize="@dimen/textsize20"
        tools:ignore="HardcodedText,RtlHardcoded" />

    <View
        android:layout_width="match_parent"
        android:layout_height="@dimen/line_1"
        android:background="@color/error_bg" />

    <TextView
        android:id="@+id/cancel"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/shape_dialog_bottom_bg"
        android:gravity="center"
        android:padding="@dimen/margin15"
        android:text="取消"
        android:textColor="@color/bottom_blue"
        android:textSize="@dimen/textsize20"
        tools:ignore="HardcodedText,RtlHardcoded" />
</LinearLayout>

第三步 主代码 

public class CameraActivity extends AppCompatActivity implements View.OnClickListener{

    private View inflate;
    private TextView camera;
    private TextView pic;
    private TextView cancel;
    private Dialog dialog;
Button  dianji;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_camera);

dianji  = (Button)findViewById(R.id.dianji);
dianji.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        show(view);
    }
});




        }



    public void show(View view){
        dialog = new Dialog(this,R.style.DialogTheme);
        //填充对话框的布局
        inflate = LayoutInflater.from(this).inflate(R.layout.ceshi, null);
        //初始化控件
        camera = (TextView) inflate.findViewById(R.id.camera);
        pic = (TextView) inflate.findViewById(R.id.pic);
        cancel = (TextView) inflate.findViewById(R.id.cancel);
        camera.setOnClickListener(this);
        pic.setOnClickListener(this);
        cancel.setOnClickListener(this);
        //将布局设置给Dialog
        dialog.setContentView(inflate);
        //获取当前Activity所在的窗体
        Window dialogWindow = dialog.getWindow();
        //设置Dialog从窗体底部弹出
        dialogWindow.setGravity( Gravity.BOTTOM);
        //获得窗体的属性
        WindowManager.LayoutParams lp = dialogWindow.getAttributes();
        lp.y = 20;//设置Dialog距离底部的距离
//       将属性设置给窗体
        dialogWindow.setAttributes(lp);
        dialog.show();//显示对话框
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()){
            case R.id.camera:
                Toast.makeText(this,"点击了拍照",Toast.LENGTH_SHORT).show();
                break;
            case R.id.pic:
                Toast.makeText(this,"点击了从相册选择",Toast.LENGTH_SHORT).show();
                break;
            case R.id.cancel:
                dialog.dismiss();
                break;
        }

    }

}

对应的style 里面弹出框的样式

    <style name="DialogTheme" parent="@android:style/Theme.Dialog">
        <!-- 边框 -->
        <item name="android:windowFrame">@null</item>
        <!-- 是否浮现在activity之上 -->
        <item name="android:windowIsFloating">true</item>
        <!-- 半透明 -->
        <item name="android:windowIsTranslucent">true</item>
        <!-- 无标题 -->
        <item name="android:windowNoTitle">true</item>
        <item name="android:background">@android:color/transparent</item>
        <!-- 背景透明 -->
        <item name="android:windowBackground">@android:color/transparent</item>
        <!-- 模糊 -->
        <item name="android:backgroundDimEnabled">true</item>
        <!-- 遮罩层 -->
        <item name="android:backgroundDimAmount">0.5</item>
    </style>
