1，点击添加附件按钮后的弹框：画面
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<LinearLayout
android:layout_margin="10dp"
android:paddingBottom="10dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="vertical" >
<Button
android:id="@+id/btn_pop_album"
android:layout_width="match_parent"
android:layout_height="@dimen/annex_btn_height"
android:text="本地相册"
android:background="#ffff"
android:textSize="@dimen/text_size" />
<Button
android:id="@+id/btn_pop_camera"
android:layout_width="match_parent"
android:layout_height="@dimen/annex_btn_height"
android:text="相机拍摄"
android:background="#ffff"
android:textSize="@dimen/text_size" />
<Button
android:id="@+id/btn_pop_cancel"
android:layout_width="match_parent"
android:layout_height="@dimen/annex_btn_height"
android:layout_marginTop="@dimen/margin_top"
android:background="#ffff"
android:text="取消"
android:textSize="@dimen/text_size" />
</LinearLayout>
</RelativeLayout>
2，后台调用弹框的按钮事件
//弹出框
private void showPopueWindow() {
View popView = View.inflate(this, R.layout.annex_layout, null);
Button bt_album = (Button) popView.findViewById(R.id.btn_pop_album);
Button bt_camera = (Button) popView.findViewById(R.id.btn_pop_camera);
Button bt_cancle = (Button) popView.findViewById(R.id.btn_pop_cancel);
//获取屏幕宽高
int weight = getResources().getDisplayMetrics().widthPixels;
int height = getResources().getDisplayMetrics().heightPixels * 1 / 3;
final PopupWindow popupWindow = new PopupWindow(popView, weight, height);
popupWindow.setFocusable(true);
//点击外部popueWindow消失
popupWindow.setOutsideTouchable(true);
bt_album.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
openAlbum();//打开相册
popupWindow.dismiss();
}
});
bt_camera.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// openCamra();
//查看运行时权限
checkCameraPermission();
popupWindow.dismiss();
}
});
bt_cancle.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
popupWindow.dismiss();
}
});
//popupWindow消失屏幕变为不透明
popupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {
@Override
public void onDismiss() {
WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.alpha = 1.0f;
getWindow().setAttributes(lp);
}
});
//popupWindow出现屏幕变为半透明
WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.alpha = 0.5f;
getWindow().setAttributes(lp);
popupWindow.showAtLocation(popView, Gravity.BOTTOM, 0, 0);
}
3，打开相册
/**
* 打开系统相册
*/
private void openAlbum() {
//只打开相册
Intent intent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 1004);
}
4，打开相机
/**
* 调用系统相机
*/
private void openCamra() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
//创建图片保存路径
File file = Utils.creatImageFile();
if (file == null) {
Toast.makeText(getApplicationContext(), "文件创建不成功", Toast.LENGTH_SHORT).show();
return;
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N){//大于24时需要使用FileProvider 1，在res下建一个XML文件夹，创建一个photofile.xml的文件，2，在AndroidManifest.xml里注册Provider
mOutPutFileUri = FileProvider.getUriForFile(this, "com.liveyc.jwbzgl.fileprovider", file);//第二个参数为包名+fileprovider
}else {
mOutPutFileUri = Uri.fromFile(file);
}
intent.putExtra(MediaStore.EXTRA_OUTPUT, mOutPutFileUri);
startActivityForResult(intent, 1003);
}
5.其他方法
//选择相册或相机，选中某张图后调用的方法
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
ContentResolver cr = this.getContentResolver();
String ImgPath = "";
String fileName = "";
Bitmap curBitmap = null;
switch (requestCode) {
case 1003:
if (mOutPutFileUri != null) {
try {
curBitmap = BitmapFactory.decodeStream(cr.openInputStream(mOutPutFileUri));
//图片路径
ImgPath = mOutPutFileUri.getPath();
//图片名字
fileName =Utils.pathToFileName(ImgPath);
} catch (FileNotFoundException e) {
Log.e("Exception", e.getMessage(), e);
}
}
break;
case 1004: {
if (data != null) {
Uri uri = data.getData();
try {
//显示图片
curBitmap = BitmapFactory.decodeStream(cr.openInputStream(uri));
//获取图片路径
ImgPath = getRealFilePath(uri);
//获取文件名
fileName = Utils.pathToFileName(ImgPath);
// cursor.close();
} catch (FileNotFoundException e) {
Log.e("Exception", e.getMessage(), e);
}
}
break;
}
}
//做处理
//保存数据
int viewTag = detailList.size();
AttachmentModel model = new AttachmentModel();
model.setId("" +viewTag);
model.setName(fileName);
model.setRealName(ImgPath);
detailList.add(model);
//添加控件
addSubView(curBitmap, viewTag);
if (detailList.size() == maxNum){
btnUpload.setVisibility(View.INVISIBLE);
}
}
}
public String getRealFilePath( final Uri uri ) {
if ( null == uri ) return null;
final String scheme = uri.getScheme();
String data = null;
if ( scheme == null )
data = uri.getPath();
else if ( ContentResolver.SCHEME_FILE.equals( scheme ) ) {
data = uri.getPath();
} else if ( ContentResolver.SCHEME_CONTENT.equals( scheme ) ) {
Cursor cursor = getContentResolver().query( uri, new String[] { MediaStore.Images.ImageColumns.DATA }, null, null, null );
if ( null != cursor ) {
if ( cursor.moveToFirst() ) {
int index = cursor.getColumnIndex( MediaStore.Images.ImageColumns.DATA );
if ( index > -1 ) {
data = cursor.getString( index );
}
}
cursor.close();
}
}
return data;
}
//获取运行时权限
private void checkCameraPermission(){
if (Build.VERSION.SDK_INT>=Build.VERSION_CODES.M){
if( (ActivityCompat.checkSelfPermission(this, Manifest.permission.CAMERA)!= PackageManager.PERMISSION_GRANTED)&& (ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED)){
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.CAMERA,Manifest.permission.WRITE_EXTERNAL_STORAGE},1006);
}else {
openCamra();
}
}else {
openCamra();
}
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
if (requestCode == 1006){ //checkCameraPermission
if ((grantResults[0] == PackageManager.PERMISSION_GRANTED) && (grantResults[1] == PackageManager.PERMISSION_GRANTED)){
openCamra();
}
}else {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
//添加图片控件
private void addSubView(Bitmap curBitmap, int viewTag) {
View imageLayout = View.inflate(this, R.layout.image_layout, null);
imageLayout.setTag(viewTag);
ImageView image = (ImageView) imageLayout.findViewById(R.id.image);
Button delete = (Button) imageLayout.findViewById(R.id.delete);
delete.setOnClickListener(uploadListener);
image.setImageBitmap(curBitmap);
uploadLinearLayout.addView(imageLayout);
}
6.FileProvider相关
photofile.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<paths>
<root-path name="my_image" path=""/>
</paths>
</resources>
在AndroidManifest.xml里注册Provider:
<provider
android:authorities="com.liveyc.jwbzgl.fileprovider"
android:name="android.support.v4.content.FileProvider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/photofile"/>
</provider>
image_layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="85dp"
android:layout_height="70dp"
android:gravity="left"
android:orientation="vertical"
android:tag="1">
<Button
android:id="@+id/delete"
android:layout_width="20dp"
android:layout_height="20dp"
android:background="@mipmap/delete"
android:textSize="@dimen/text_size" />
<ImageView
android:id="@+id/image"
android:layout_width="50dp"
android:layout_height="50dp"
android:scaleType="fitXY"
android:layout_marginLeft="@dimen/margin_left" />
</LinearLayout>
