webview文件上传需要重写webchromeclient里面的几个方法：
import android.app.Activity;
import android.content.ContentValues;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Environment;
import android.provider.MediaStore;
import android.webkit.ValueCallback;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import com.imyuu.travel.utils.SPHelper;
import java.io.File;

public class UploadFileWebChromeClient extends WebChromeClient {
public ValueCallback uploadMsg;
public ValueCallback uploadMsgOver5;
private Activity activity;
public static final int FILE_CHOOSER_RESULT_CODE = 0x5423;
@SuppressWarnings("deprecation")
public UploadFileWebChromeClient(Activity activity) {
this.activity = activity;
}
@Override
public void onProgressChanged(WebView view, int newProgress) {
super.onProgressChanged(view, newProgress);
}
// Android > 5.0
@Override
public boolean onShowFileChooser(WebView webView, ValueCallback filePathCallback, FileChooserParams fileChooserParams) {
// TODO 自动生成的方法存根
uploadMsgOver5 = filePathCallback;
this.activity.startActivityForResult(createDefaultOpenableIntent(), FILE_CHOOSER_RESULT_CODE);
return true;
}
@SuppressWarnings("static-access")
public void openFileChooser(ValueCallback uploadMsg, String acceptType, String capture) {
this.uploadMsg = uploadMsg;
this.activity.startActivityForResult(createDefaultOpenableIntent(), this.FILE_CHOOSER_RESULT_CODE);
}
// 3.0 +
@SuppressWarnings("static-access")
public void openFileChooser(ValueCallback uploadMsg, String acceptType) {
this.uploadMsg = uploadMsg;
this.activity.startActivityForResult(createDefaultOpenableIntent(), this.FILE_CHOOSER_RESULT_CODE);
}
// Android < 3.0
@SuppressWarnings("static-access")
public void openFileChooser(ValueCallback uploadMsg) {
this.uploadMsg = uploadMsg;
this.activity.startActivityForResult(createDefaultOpenableIntent(), this.FILE_CHOOSER_RESULT_CODE);
}
private Intent createDefaultOpenableIntent() {
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "image/*");
Intent chooser = createChooserIntent(createCameraIntent());
chooser.putExtra(Intent.EXTRA_INTENT, i);
return chooser;
}
private Intent createChooserIntent(Intent... intents) {
Intent chooser = new Intent(Intent.ACTION_CHOOSER);
chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, intents);
chooser.putExtra(Intent.EXTRA_TITLE, "选择图片");
return chooser;
}
@SuppressWarnings("static-access")
private Intent createCameraIntent() {
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File externalDataDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
File cameraDataDir = new File(externalDataDir.getAbsolutePath() + File.separator + ".imyuu");
cameraDataDir.mkdirs();
String mCameraFilePath = cameraDataDir.getAbsolutePath() + File.separator + System.currentTimeMillis() + ".jpg";
SPHelper.setParam(this.activity, "cameraImgPath", mCameraFilePath);
cameraIntent.putExtra(MediaStore.Images.Media.ORIENTATION, 0);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(mCameraFilePath)));
return cameraIntent;
}
public static Uri getImageContentUri(Context context, java.io.File imageFile) {
String filePath = imageFile.getAbsolutePath();
Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, new String[]{MediaStore.Images.Media._ID}, MediaStore.Images.Media.DATA + "=? ", new String[]{filePath}, null);
if (cursor != null && cursor.moveToFirst()) {
int id = cursor.getInt(cursor.getColumnIndex(MediaStore.MediaColumns._ID));
Uri baseUri = Uri.parse("content://media/external/images/media");
return Uri.withAppendedPath(baseUri, "" + id);
} else {
if (imageFile.exists()) {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.DATA, filePath);
return context.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
} else {
return null;
}
}
}
}
然后在对应的activity里面重写onActivityResult方法：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == UploadFileWebChromeClient.FILE_CHOOSER_RESULT_CODE) {
if (null != uploadFileWebChromeClient.uploadMsg) {
Uri result = data == null || resultCode != RESULT_OK ? null : data.getData();
if (result == null) {
String cameraImgPath = (String) SPHelper.getParam(ChatActivity.this, "cameraImgPath", "");
if (cameraImgPath == null) {
Logger.e("result1:" + result);
uploadFileWebChromeClient.uploadMsg.onReceiveValue(null);
uploadFileWebChromeClient.uploadMsg = null;
return;
}
Uri imagePathUri = ImageUtils.createImagePathUri(ChatActivity.this, cameraImgPath);
if (imagePathUri != null) {
Logger.e("result2:" + imagePathUri);
uploadFileWebChromeClient.uploadMsg.onReceiveValue(imagePathUri);
uploadFileWebChromeClient.uploadMsg = null;
}
return;
}
Logger.e("result3:" + result);
uploadFileWebChromeClient.uploadMsg.onReceiveValue(result);
uploadFileWebChromeClient.uploadMsg = null;
}
if (null != uploadFileWebChromeClient.uploadMsgOver5) {
Uri result = data == null || resultCode != RESULT_OK ? null : data.getData();
if (result == null) {
String cameraImgPath = (String) SPHelper.getParam(ChatActivity.this, "cameraImgPath", "");
if (cameraImgPath == null) {
Logger.e("result4:" + result);
uploadFileWebChromeClient.uploadMsgOver5.onReceiveValue(null);
uploadFileWebChromeClient.uploadMsgOver5 = null;
return;
}
Uri imagePathUri = ImageUtils.createImagePathUri(ChatActivity.this, cameraImgPath);
if (imagePathUri != null) {
Logger.e("result5:" + imagePathUri);
uploadFileWebChromeClient.uploadMsgOver5.onReceiveValue(new Uri[]{imagePathUri});
uploadFileWebChromeClient.uploadMsgOver5 = null;
}
return;
}
Logger.e("result6:" + result);
uploadFileWebChromeClient.uploadMsgOver5.onReceiveValue(new Uri[]{result});
uploadFileWebChromeClient.uploadMsgOver5 = null;
}
}
}
其中SPHelper是sharepreference的封装类：
import android.content.Context;
import android.content.SharedPreferences;
/**
* Created by jiangtao on 2016/12/25 12:22
* E-mail：[email protected]
*/
public class SPHelper {
/**
* 保存在手机里面的文件名
*/
private static final String FILE_NAME = "share_date";
/**
* 保存数据的方法，我们需要拿到保存数据的具体类型，然后根据类型调用不同的保存方法
*
* @param context
* @param key
* @param object
*/
public static void setParam(Context context, String key, Object object) {
String type = object.getClass().getSimpleName();
SharedPreferences sp = context.getSharedPreferences(FILE_NAME, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
if ("String".equals(type)) {
editor.putString(key, (String) object);
} else if ("Integer".equals(type)) {
editor.putInt(key, (Integer) object);
} else if ("Boolean".equals(type)) {
editor.putBoolean(key, (Boolean) object);
} else if ("Float".equals(type)) {
editor.putFloat(key, (Float) object);
} else if ("Long".equals(type)) {
editor.putLong(key, (Long) object);
}
editor.apply();
}
/**
* 得到保存数据的方法，我们根据默认值得到保存的数据的具体类型，然后调用相对于的方法获取值
*
* @param context
* @param key
* @param defaultObject
* @return
*/
public static Object getParam(Context context, String key, Object defaultObject) {
String type = defaultObject.getClass().getSimpleName();
SharedPreferences sp = context.getSharedPreferences(FILE_NAME, Context.MODE_PRIVATE);
if ("String".equals(type)) {
return sp.getString(key, (String) defaultObject);
} else if ("Integer".equals(type)) {
return sp.getInt(key, (Integer) defaultObject);
} else if ("Boolean".equals(type)) {
return sp.getBoolean(key, (Boolean) defaultObject);
} else if ("Float".equals(type)) {
return sp.getFloat(key, (Float) defaultObject);
} else if ("Long".equals(type)) {
return sp.getLong(key, (Long) defaultObject);
}
return null;
}
}
createImagePathUri是创建本地文件的Uri：
/**
* 创建一条图片地址uri,用于保存拍照后的照片
*
* @param context
* @return 图片的uri
*/
public static Uri createImagePathUri(Context context,String path) {
Uri imageFilePath;
File file = new File(path);
if (!file.exists()) {
file.mkdirs();
}
Logger.e("SDK:" + Build.VERSION.SDK_INT);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
ContentValues contentValues = new ContentValues(1);
contentValues.put(MediaStore.Images.Media.DATA, file.getAbsolutePath());
imageFilePath = context.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues);
} else {
imageFilePath = Uri.fromFile(new File(path));
}
return imageFilePath;
}
