android 新增視訊、圖片、錄音上傳（一）
阿新 • • 發佈：2019-01-26
實現一個功能，上報資訊，可以新增視訊、圖片、錄音。呼叫系統相機，所以每次只能選擇一張圖片。
//拍照
add_photo.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (commitId.equals("0")) {
Toast.makeText(getApplicationContext(), "請先儲存上面的資訊" 拍照和視訊的處理
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode== Activity.RESULT_OK){
switch(requestCode) {
case 10:
Uri uriVideo = data.getData();
Cursor cursors=this.getContentResolver().query(uriVideo, null, null, null, null);
if (cursors.moveToNext()) {
/* _data：檔案的絕對路徑 ，_display_name：檔名 */
videoPath = cursors.getString(cursors.getColumnIndex("_data"));
Toast.makeText(this, videoPath, Toast.LENGTH_SHORT).show();
//儲存視訊路徑
imagelist.add(videoPath);
setImageGrideValue();
}
break;
case 11:
Uri uri = data.getData();
Log.e(TAG, "uri = " + uri);
try {
String[] pojo = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, pojo, null, null, null);
if (cursor != null) {
ContentResolver cr = this.getContentResolver();
int colunm_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String path = cursor.getString(colunm_index);
/***
* 這裡加這樣一個判斷主要是為了第三方的軟體選擇，比如：使用第三方的檔案管理器的話，你選擇的檔案就不一定是圖片了，
* 這樣的話，我們判斷檔案的字尾名 如果是圖片格式的話，那麼才可以
*/
if (path.endsWith("jpg") || path.endsWith("png")) {
srcPath=path;
//儲存圖片路徑
imagelist.add(srcPath);
setImageGrideValue();
} else {
alert();
}
} else {
alert();
}
} catch (Exception e) {
e.printStackTrace();
}
break;
default:
break;
}
}
super.onActivityResult(requestCode, resultCode, data);
}
private void alert() {
Dialog dialog = new AlertDialog.Builder(this).setTitle("提示")
.setMessage("您選擇的不是有效的圖片")
.setPositiveButton("確定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
srcPath = null;
}
}).create();
dialog.show();
}在頁面顯示新增的視訊和照片列表（視訊使用的是預設圖片顯示）
