android 适配8.0。6.0调起手机拍照获取照片路径

用的时候直接复制即可 必要的已经写上备注，欢迎大神指点，有些代码是拼凑的，然后我自己的总结。

首先先配置：
在清单文件配置一下
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="（你的包名）.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths"></meta-data>
</provider>在rec文件下创建xml文件夹，在里面创建xml文件
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>java代码如下：

/**
* 使用相机
*/
private void useCamera() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()
+ "/test/" + System.currentTimeMillis() + ".jpg");
file.getParentFile().mkdirs();

//改变Uri  com.xykj.customview.fileprovider注意和xml中的一致
Uri uri = FileProvider.getUriForFile(this, "com.example.administrator.myapplication.fileprovider", file);
//添加权限
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
startActivityForResult(intent, REQUEST_CAMERA);
}
public void applyWritePermission() {

String[] permissions = {Manifest.permission.WRITE_EXTERNAL_STORAGE};

if (Build.VERSION.SDK_INT >= 23) {
int check = ContextCompat.checkSelfPermission(this, permissions[0]);
// 权限是否已经 授权 GRANTED---授权  DINIED---拒绝
if (check == PackageManager.PERMISSION_GRANTED) {
//调用相机
useCamera();
} else {
requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
}
} else {
useCamera();
}
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
@NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
useCamera();
} else {
// 没有获取 到权限，从新请求，或者关闭app
Toast.makeText(this, "需要存储权限", Toast.LENGTH_SHORT).show();
}
}
@Override
<
4000
strong>protected void [/b]onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1 && resultCode == RESULT_OK) {
//            Log.e("TAG", "---------" + FileProvider.getUriForFile(this, "com.xykj.customview.fileprovider", file));
//在手机相册中显示刚拍摄的图片
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(file);
String path = contentUri.getPath();
Log.e("TAGSSSSSSSSS", contentUri.toString());
//文件的路径
String absolutePath = file.getAbsolutePath();
//文件的名字
String parent = file.getName();
Log.e("TAGQQQQQQQQQ", parent + "===" + absolutePath);
mediaScanIntent.setData(contentUri);
sendBroadcast(mediaScanIntent);
//设置图片
picture.setImageBitmap(BitmapFactory.decodeFile(file.getAbsolutePath()));
}else{
File photoFile = new File(photoPath);
if (photoFile.exists()) {
//通过图片地址将图片加载到bitmap里面
Bitmap bm = BitmapFactory.decodeFile(photoFile.getAbsolutePath());
//将拍摄的照片显示到界面上
//这是返回来的路径
//                    results.confirm(pathsa);
Toast.makeText(MainActivity.this, "通过", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(MainActivity.this, "图片文件不存在", Toast.LENGTH_LONG).show();
}
}
}
}

/**
* 拍照的，照片路径
*/
public void jsPath() {
//获取SD卡安装状态
String state = Environment.getExternalStorageState();
if (state.equals(Environment.MEDIA_MOUNTED)) {

//设置图片保存路径
photoPath = SAVED_IMAGE_PATH + "/" + System.currentTimeMillis() + ".png";

File imageDir = new File(photoPath);
if (!imageDir.exists()) {
try {
//根据一个 文件地址生成一个新的文件用来存照片
imageDir.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
takePhotoByMethod1();
} else {
Toast.makeText(MainActivity.this, "SD卡未插入", Toast.LENGTH_SHORT).show();
}
}
private void takePhotoByMethod1() {
//实例化intent,指向摄像头
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
//根据路径实例化图片文件
File photoFile = new File(photoPath);
//设置拍照后图片保存到文件中
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
//启动拍照activity并获取返回数据
startActivityForResult(intent, REQUEST_CAMERA);
}

上面的是必要的执行代码。

下边：switch (v.getId()) {
case R.id.take_photo:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N){
applyWritePermission();
}else{
jsPath();
}
break;

}

点击这个按钮就可以实现， 新手第一 次写 请多多指教。
