还是先上图
PopupWindow.jpg
1.新建一个类PhotoPopupWindow
/**
* Created by Administrator on 2019/7/16 0016.
*/
public class PhotoPopupWindow extends PopupWindow {
private View mView; // PopupWindow 菜单布局
private Context mContext; // 上下文参数
private View.OnClickListener mSelectListener; // 相册选取的点击监听器
private View.OnClickListener mCaptureListener; // 拍照的点击监听器
public PhotoPopupWindow(Activity context, View.OnClickListener selectListener, View.OnClickListener captureListener) {
super(context);
this.mContext = context;
this.mSelectListener = selectListener;
this.mCaptureListener = captureListener;
init();
}
/**
* 设置布局以及点击事件
*/
private void init() {
LayoutInflater inflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view= inflater.inflate(R.layout.popu_layout, null);
Button btn_camera = (Button) mView.findViewById(R.id.btn_camera);
Button btn_select = (Button) mView.findViewById(R.id.btn_select);
Button btn_cancel = (Button) mView.findViewById(R.id.btn_cancel);
btn_select.setOnClickListener(mSelectListener);
btn_camera.setOnClickListener(mCaptureListener);
btn_cancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
}
});
// 导入布局
this.setContentView(mView);
// 设置动画效果
this.setAnimationStyle(R.style.popwindow_anim_style);
this.setWidth(WindowManager.LayoutParams.MATCH_PARENT);
this.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
// 设置可触
this.setFocusable(true);
ColorDrawable drawable = new ColorDrawable(0x0000000);
this.setBackgroundDrawable(drawable );
// 单击弹出窗以外关闭窗口
view.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
int height = mView.findViewById(R.id.ll_pop).getTop();
int y = (int) event.getY();
if (event.getAction() == MotionEvent.ACTION_UP) {
if (y < height) {
dismiss();
}
}
return true;
}
});
}
}
2.popu_layout.xml 布局文件
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#66000000">
<LinearLayout
android:id="@+id/ll_pop"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="@dimen/dp_15"
android:layout_marginRight="@dimen/dp_15"
android:orientation="vertical"
android:layout_alignParentBottom="true">
<Button
android:id="@+id/icon_btn_camera"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/white_btn_top"
android:textColor="@color/colorMainGreen"
android:text="拍照"/>
<View
android:layout_width="match_parent"
android:layout_height="@dimen/dp_1"
android:background="#eee"/>
<Button
android:id="@+id/icon_btn_select"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/white_btn_bottom"
android:textColor="@color/colorMainGreen"
android:text="相册选择"/>
<Button
android:id="@+id/icon_btn_cancel"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="@dimen/dp_10"
android:layout_marginBottom="@dimen/dp_15"
android:background="@drawable/white_btn"
android:textColor="@color/colorMainGreen"
android:text="取消"/>
</LinearLayout>
</RelativeLayout>
white_btn_top.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@android:color/white" />
<corners android:topLeftRadius="@dimen/dp_10"
android:topRightRadius="@dimen/dp_10"
android:bottomRightRadius="0dp"
android:bottomLeftRadius="0dp"/>
<stroke android:width="0dp" android:color="@android:color/white" />
</shape>
white_btn_bottom.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@android:color/white" />
<corners android:topLeftRadius="0dp"
android:topRightRadius="0dp"
android:bottomRightRadius="@dimen/dp_10"
android:bottomLeftRadius="@dimen/dp_10"/>
<stroke android:width="0dp" android:color="@android:color/white" />
</shape>
white_btn.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@android:color/white"/>
<corners android:radius="@dimen/dp_10"/>
<stroke android:width="0dp" android:color="@android:color/white" />
</shape>
显示及关闭动画
1.在style中添加：
<style name="popwindow_anim_style">
<item name="android:windowEnterAnimation">@anim/popup_show</item>
<item name="android:windowExitAnimation">@anim/popup_gone</item>
</style>
2.在res下新建anim文件夹
2.1 新建popup_show.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha
android:duration="300"
android:fromAlpha="0.0"
android:toAlpha="1.0" />
</set>
2.2 新建popup_gone.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha
android:duration="200"
android:fromAlpha="1.0"
android:toAlpha="0.0" />
</set>
OK, 完成！
在页面中引用：
PhotoPopupWindow mPhotoPopupWindow = new PhotoPopupWindow(调用页面.this, new View.OnClickListener() {
@Override
public void onClick(View v) {
// 进入相册选择
System.out.println("进入相册选择");
// 文件权限申请
if (ContextCompat.checkSelfPermission(UserInfoActivity.this,
Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
// 权限还没有授予，进行申请
ActivityCompat.requestPermissions(UserInfoActivity.this,
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 200); // 申请的 requestCode 为 200
} else {
// 如果权限已经申请过，直接进行图片选择
mPhotoPopupWindow.dismiss();
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
// 判断系统中是否有处理该 Intent 的 Activity
if (intent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(intent, REQUEST_IMAGE_GET);
} else {
Toast.makeText(UserInfoActivity.this, "未找到图片查看器", Toast.LENGTH_SHORT).show();
}
}
}
}, new View.OnClickListener() {
@Override
public void onClick(View v) {
// 拍照
System.out.println("拍照");
// 拍照及文件权限申请
if (ContextCompat.checkSelfPermission(调用页面.this,
Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED
|| ContextCompat.checkSelfPermission(调用页面.this,
Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
// 权限还没有授予，进行申请
ActivityCompat.requestPermissions(调用页面.this,
new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}, 300); // 申请的 requestCode 为 300
} else {
// 权限已经申请，直接拍照
mPhotoPopupWindow.dismiss();
CameraUtil.openCamera(调用页面.this);
}
}
});
View rootView = LayoutInflater.from(调用页面.this).inflate(调用页面的布局, null);
mPhotoPopupWindow.showAtLocation(rootView,
Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0, 0);
以上就是关于PopupWindow的所有。
下面附上一个调用系统相机的工具类，亲测可用，妈妈再也不用担心我的fileprovider了！！
public class CameraUtil {
public static File tempFile;
public static final int PHOTO_REQUEST_CAREMA = 1;// 拍照
public static final int CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE = 2;// 拍摄视频
private static final String IMAGE_FILE_NAME = "icon.jpg";
/**
* 打开相机拍照
*
* @param activity
*/
public static void openCamera(Activity activity) {
//获取系统版本
int currentapiVersion = android.os.Build.VERSION.SDK_INT;
// 激活相机
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// 判断存储卡是否可以用，可用进行存储
if (hasSdcard()) {
SimpleDateFormat timeStampFormat = new SimpleDateFormat(
"yyyy_MM_dd_HH_mm_ss");
String filename = timeStampFormat.format(new Date());
tempFile = new File(Environment.getExternalStorageDirectory(),
filename + ".jpg");
if (currentapiVersion < 24) {
// 从文件中创建uri
Uri uri = Uri.fromFile(tempFile);
intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
} else {
//兼容android7.0 使用共享文件的形式
ContentValues contentValues = new ContentValues(1);
contentValues.put(MediaStore.Images.Media.DATA, tempFile.getAbsolutePath());
Uri uri = activity.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues);
intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
}
}
// 开启一个带有返回值的Activity，请求码为PHOTO_REQUEST_CAREMA
activity.startActivityForResult(intent, PHOTO_REQUEST_CAREMA);
}
/**
* 打开相机录像
*/
public static void startToVideo(Activity activity) {
//獲取系統版本
int currentapiVersion = android.os.Build.VERSION.SDK_INT;
Uri fileUri = null;
File file = null;
Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
try {
file = createMediaFile();
if (file.exists()) {
fileUri = Uri.fromFile(file); // create a file to save the video
}
} catch (IOException e) {
e.printStackTrace();
}
if (currentapiVersion < 24) {
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); // set the video image quality to high
} else {
//兼容android7.0
ContentValues contentValues = new ContentValues(1);
contentValues.put(MediaStore.Images.Media.DATA, file.getAbsolutePath());
Uri uri = activity.getApplication().getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues);
intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
}
// start the Video Capture Intent
activity.startActivityForResult(intent, CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE);
}
/*
* 判断sdcard是否被挂载
*/
public static boolean hasSdcard() {
return Environment.getExternalStorageState().equals(
Environment.MEDIA_MOUNTED);
}
/**
* 创建保存录制得到的视频文件
*
* @return
* @throws IOException
*/
public static File createMediaFile() throws IOException {
if (hasSdcard()) {
File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_MOVIES), "CameraVideos");
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
return null;
}
}
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "VID_" + timeStamp;
String suffix = ".mp4";
File mediaFile = new File(mediaStorageDir + File.separator + imageFileName + suffix);
return mediaFile;
}
return null;
}
}
权限处理回调
/**
* 处理权限回调结果
*/
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
switch (requestCode) {
case 200:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
mPhotoPopupWindow.dismiss();
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
// 判断系统中是否有处理该 Intent 的 Activity
if (intent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(intent, REQUEST_IMAGE_GET);
} else {
MyToast.getToast(getApplicationContext(), "未找到图片查看器！");
}
} else {
mPhotoPopupWindow.dismiss();
MyToast.getToast(getApplicationContext(), "权限被拒绝无法使用该功能！");
}
break;
case 300:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
mPhotoPopupWindow.dismiss();
CameraUtil.openCamera(UserInfoActivity.this);
} else {
mPhotoPopupWindow.dismiss();
MyToast.getToast(getApplicationContext(), "权限被拒绝无法使用该功能！");
}
break;
}
}
相机 相册回调处理
private static final int REQUEST_IMAGE_GET = 0;
private static final int REQUEST_IMAGE_CAPTURE = 1;
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// 回调成功
if (resultCode == RESULT_OK) {
switch (requestCode) {
// 相册选取
case REQUEST_IMAGE_GET:
try {
Uri uri = data.getData();
userInfoRiv.setImageURI(uri);
//根据uri获取bitmap
} catch (NullPointerException e) {
e.printStackTrace();
}
break;
// 拍照
case REQUEST_IMAGE_CAPTURE:
System.out.println("拍照返回成功");
Uri uri = Uri.fromFile(CameraUtil.tempFile);
userInfoRiv.setImageURI(uri);
break;
}
}
}
里面用到的自定义MyToast类，有兴趣的可以了解下！
