Question

LinearLayout table = (LinearLayout)findViewById(R.id.linearlayout);

btnControl = new Button(this);
    btnControl.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
    btnControl.setPadding(0,40,0,40);//x,y,w,h
    btnControl.setBackgroundColor(Color.parseColor("#1C344E"));
    btnControl.setTextColor(Color.WHITE);
    setMargins(btnControl, 50, 50, 50, 50);

btnLogs = new Button(this);
        btnLogs.setLayoutParams(new LayoutParams(380, LayoutParams.WRAP_CONTENT));
        btnLogs.setPadding(0,40,0,40);//x,y,w,h
        btnLogs.setBackgroundColor(Color.parseColor("#1C344E"));
        btnLogs.setTextColor(Color.WHITE);
        setMargins(btnLogs, 50, 50, 50, 50);
        btnLogs.setId(5);
        btnLogs.setOnClickListener(this);

        btnTermLogs = new Button(this);
        btnTermLogs.setLayoutParams(new LayoutParams(380, LayoutParams.WRAP_CONTENT));
        btnTermLogs.setPadding(0,40,0,40);//x,y,w,h
        btnTermLogs.setBackgroundColor(Color.parseColor("#CC6675"));
        btnTermLogs.setTextColor(Color.WHITE);
        setMargins(btnLogs, 50, 50, 50, 50);
        btnTermLogs.setId(6);
        btnTermLogs.setOnClickListener(this);

btnLogout = new Button(this);
    btnLogout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
    btnLogout.setPadding(0,40,0,40);//x,y,w,h
    btnLogout.setBackgroundColor(Color.parseColor("#CC6675"));
    btnLogout.setTextColor(Color.WHITE);

    table.addView(btnLogs);
        table.addView(btnTermLogs);

我希望两个按钮水平对齐。然而，它只是垂直对齐，我不想要。

我的按钮看起来像这样：

我想要的是这样：

Answer 1

尝试以下功能。它会有所帮助

public void addButtons(){
    LinearLayout table = (LinearLayout)findViewById(R.id.linearlayout);

    LinearLayout linearLayout1 = new LinearLayout(this);
    linearLayout1.setOrientation(LinearLayout.VERTICAL);
    LinearLayout.LayoutParams LayoutParamsview = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);

    Button button1 = new Button(this);
    button1.setText("Btn 1");
    button1.setLayoutParams(LayoutParamsview);

    linearLayout1.addView(button1);
    table.addView(linearLayout1);

    //
    LinearLayout linearLayout2 = new LinearLayout(this);
    linearLayout2.setOrientation(LinearLayout.HORIZONTAL);

    Button button2 = new Button(this);
    button2.setText("Btn 2");
    button2.setLayoutParams(LayoutParamsview);

    Button button3 = new Button(this);
    button3.setText("Btn 3");
    button3.setLayoutParams(LayoutParamsview);

    linearLayout2.addView(button2);
    linearLayout2.addView(button3);
    table.addView(linearLayout2);

    //
    LinearLayout linearLayout3 = new LinearLayout(this);
    linearLayout3.setOrientation(LinearLayout.VERTICAL);

    Button button4 = new Button(this);
    button4.setText("Btn 4");
    button4.setLayoutParams(LayoutParamsview);

    linearLayout3.addView(button4);
    table.addView(linearLayout3);

}

Answer 2

您应该使用setLayoutParams
添加 setOrientation(LinearLayout.HORIZONTAL);

设置与此视图关联的布局参数。这些供应此视图的父级参数指定它应该如何安排。 ViewGroup.LayoutParams有许多子类，和这些对应于ViewGroup的不同子类负责安排他们的孩子。

代码结构

    LinearLayout table = (LinearLayout)findViewById(R.id.linearlayout);
    table.setOrientation(LinearLayout.HORIZONTAL);

    Button Btn1 = new Button(Activity.this);
    Btn1.setText("Button 1");
    LinearLayout.LayoutParams childParam = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT);
    childParam.weight = 0.5f;
    Btn1.setLayoutParams(childParam);

    Button Btn2 = new Button(Activity.this);
    Btn2.setText("Button 2");
    LinearLayout.LayoutParams childParam2 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    childParam2.weight = 0.5f;
    Btn2.setLayoutParams(childParam2);

    table.addView(Btn1);
    table.addView(Btn2);

Answer 3

您可以创建另一个包含水平- name: Snapshoting the instance... ec2_snapshot: region: us-west-2 volume_id: "{{ item }}" description: "Snapshot test by" with_items: "{{ ec2_facts | json_query('instances[].block_device_mapping[].volume_id') }}"的{{1}}文件，然后对其进行充气并将两个按钮插入其中，然后将整个水平XML添加到垂直LinearLayout {1}}：

创建LinearLayout文件，例如LinearLayout：
```
XML
```

在您的活动中使用此方法来夸大horizontal_layout.xml：

<LinearLayout
    android:id="@+id/horizontal_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

// You will insert the buttons programmatically.

</LinearLayout>

Answer 4

水平线性布局支持从左到右的小部件方法，何时应用程序开发人员选择线性布局中的水平方向将自动开始向左侧添加组件和小部件添加后右侧。所以这是完整的一步一步以编程方式创建水平线性布局的教程机器人。

编写此代码

     //Creating LinearLayout.
     LinearLayout Horizontallinearlayout = new LinearLayout(this);

     //Setting up LinearLayout Orientation
     Horizontallinearlayout.setOrientation(LinearLayout.HORIZONTAL);

     LayoutParams Horizontallinearlayoutlayoutparams = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT); 

     setContentView(Horizontallinearlayout, Horizontallinearlayoutlayoutparams);

     LayoutParams LayoutParamsview = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

     //Creating textview .
     Button button1 = new Button(this);
     Button button2 = new Button(this);

     //Adding text to TextView.
     button1.setText("First Button");
     button2.setText("Second Button");

     button1.setLayoutParams(LayoutParamsview);
     button2.setLayoutParams(LayoutParamsview);

     //Adding textview to linear layout using Add View function.
     Horizontallinearlayout.addView(button1);
     Horizontallinearlayout.addView(button2);

希望这有助于你

Answer 5

使用table.setOrientation(LinearLayout.HORIZONTAL);。

希望它有所帮助。
