標準 看完這個帖子一定看看這個， 兩個結合 ， 實現  拍照 相簿 回撥

主頁面佈局  這裡對應的就是一個點選事件 實現 ，

<?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="測試"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />
</LinearLayout>
 

第二步對應 在建立 底部彈出框的佈局

<?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="相簿"
        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 主程式碼 

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);
        //填充對話方塊的佈局
        inflate = LayoutInflater.from(this).inflate(R.layout.ceshi, null);
        //初始化控制元件
        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);
        //將佈局設定給Dialog
        dialog.setContentView(inflate);
        //獲取當前Activity所在的窗體
        Window dialogWindow = dialog.getWindow();
        //設定Dialog從窗體底部彈出
        dialogWindow.setGravity( Gravity.BOTTOM);
        //獲得窗體的屬性
        WindowManager.LayoutParams lp = dialogWindow.getAttributes();
        lp.y = 20;//設定Dialog距離底部的距離
//       將屬性設定給窗體
        dialogWindow.setAttributes(lp);
        dialog.show();//顯示對話方塊
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()){
            case R.id.camera:
                Toast.makeText(this,"點選了拍照",Toast.LENGTH_SHORT).show();
                break;
            case R.id.pic:
                Toast.makeText(this,"點選了從相簿選擇",Toast.LENGTH_SHORT).show();
                break;
            case R.id.cancel:
                dialog.dismiss();
                break;
        }

    }

}
 

對應的style 裡面彈出框的樣式

    <style name="DialogTheme" parent="@android:style/Theme.Dialog">
        <!-- 邊框 -->
        <item name="android:windowFrame">@null</item>
        <!-- 是否浮現在activity之上 -->
        <item name="android:windowIsFloating">true</item>
        <!-- 半透明 -->
        <item name="android:windowIsTranslucent">true</item>
        <!-- 無標題 -->
        <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>
        <!-- 遮罩層 -->
        <item name="android:backgroundDimAmount">0.5</item>
    </style>
