如何將相機中的圖片添加到Android中的ImageView中？

-1

我的Java類代碼有一個Button，它允許用戶訪問攝像頭，拍照，然後將該圖片添加到ImageView。
我未能實現此功能。如何將相機中的圖片添加到Android中的ImageView中？

這裏是我的Java代碼：

sir你是否搜索過你的問題的stackoverflow？ – Elltz

是的，刻苦。因爲在我想通過所有搜索找到後，我無法弄清楚這一點，所以我會發布我的代碼以查看發生了什麼。 –

[從攝像頭獲取圖片到ImageView Android]可能的重複（http://stackoverflow.com/questions/15799307/get-image-from-camera-into-imageview-android） – jlopez

使用本

@Override 
//result of dispatchTakePictureIntent 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) { 
    mImageView.setImageBitmap(new BitmapDrawable(getBaseContext(), 
         getPath(data.getData(),getBaseContext()))); 
    } 
}

添加這個方法太

public String getPath(Uri uri,Context c) { 
    String[] projection = { MediaStore.Images.Media.DATA }; 
    Cursor cursor = c.getContentResolver().query(uri, projection, null, null, null); 
    if (cursor == null) 
     return null; 
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); 
    cursor.moveToFirst(); 
    String s=cursor.getString(column_index); 
    cursor.close(); 
    return s; 
}

先生，這個問題的答案是對計算器洙許多問題重複，我不知道你，但如果你沒問題，然後這個答案解決了你的問題不接受它並刪除了問題，所以幫助清理網站，畢竟你的問題已經解決了
