按钮并排LinearLayout(Button side by side LinearLayout)

大家好,我正在尝试将按钮并排,但我似乎无法让它工作。 我真的试过搞乱并尝试谷歌但失败了。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity"
android:orientation="vertical"
android:weightSum="1">

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Name"
    android:id="@+id/name" />

<EditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/nameText" />

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="New Button"
    android:id="@+id/button" />

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="New Button"
    android:id="@+id/button"
    android:layout_gravity="right" />

我怎么会这样做?


Hello guys I am trying to make the buttons side by side but I cant seem to get it work. I really tried messing around and tried google but failed.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity"
android:orientation="vertical"
android:weightSum="1">

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Name"
    android:id="@+id/name" />

<EditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/nameText" />

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="New Button"
    android:id="@+id/button" />

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="New Button"
    android:id="@+id/button"
    android:layout_gravity="right" />

How would I do it guys?

你需要序列化你的params字典,然后对它进行字符串编码,因为你的body参数中有一个JSON对象。 试试这个:

    NSDictionary *params = @{@"email": @"email@gmail.com", @"name": @"myName"};
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:params options:0 error:nil];
    NSString *json = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
    NSDictionary *dict = @{@"body":json};
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    [manager POST:@"http://myURL.com/user" parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"JSON: %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSString *myString = [[NSString alloc] initWithData:operation.request.HTTPBody encoding:NSUTF8StringEncoding];
        NSLog(@"Error: %@", myString);
    }];

You need to serialize your params dictionary and then string encode it, since your body parameter has a JSON object in it. Try using this :

    NSDictionary *params = @{@"email": @"email@gmail.com", @"name": @"myName"};
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:params options:0 error:nil];
    NSString *json = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
    NSDictionary *dict = @{@"body":json};
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    [manager POST:@"http://myURL.com/user" parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"JSON: %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSString *myString = [[NSString alloc] initWithData:operation.request.HTTPBody encoding:NSUTF8StringEncoding];
        NSLog(@"Error: %@", myString);
    }];
