Question

我想要添加的这两个按钮可以动态布局。

Button settingsButton = new Button(this);
settingsButton.setText("Settings");
View view = findViewById(R.id.content_frame);
int width = view.getWidth() / 5;
int height = view.getHeight() / 5;
settingsButton.setLayoutParams(new LinearLayout.LayoutParams(Math.max(width, height), Math.min(width, height)));
((ViewGroup) view).addView(settingsButton);

Button entryButton = new Button(this);
entryButton.setText("add Entry");
entryButton.setLayoutParams(new LinearLayout.LayoutParams(Math.max(width, height), Math.min(width, height)));

((ViewGroup) view).addView(entryButton);

现在，为了使按钮不显示在彼此之上，我尝试给第二个按钮一个边距，如：

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(Math.max(width, height), Math.min(width, height));
params.setMargins(Math.max(width, height), 0, 0, 0);

然后

((ViewGroup) view).addView(entryButton, params);

或

entryButton.setLayoutParams(params);
((ViewGroup) view).addView(entryButton);

两者都没有改变任何东西。有任何想法吗？谢谢！

Answer 1

您可能必须使用

ViewGroup.MarginLayoutParams.setMargins

做这样的事情就可以了：

LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.HORIZONTAL);

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
     LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);

layoutParams.setMargins(10, 10, 10, 10);

Button button = new Button(getActivity());
button.setText("My Button");
linearLayout.addView(button, layoutParams);

Answer 2

我尝试使用LinearLayout。它工作正常。

您的布局文件将类似于

<RelativeLayout 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"
    tools:context=".MainActivity" >

<LinearLayout 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:id="@+id/rlParent">


</LinearLayout>
</RelativeLayout>

在oncreate里面，我们需要像

一样

     Button settingsButton = new Button(this);
settingsButton.setText("Settings");
settingsButton.setTextColor(Color.BLACK);
settingsButton.setHeight(LayoutParams.WRAP_CONTENT);
settingsButton.setWidth(LayoutParams.WRAP_CONTENT);
View view = findViewById(R.id.rlParent);        
          ((ViewGroup) view).addView(settingsButton,0);
          Button entryButton = new Button(this);
entryButton.setText("add Entry");
entryButton.setTextColor(Color.BLACK);
entryButton.setHeight(LayoutParams.WRAP_CONTENT);
entryButton.setWidth(LayoutParams.WRAP_CONTENT);
((ViewGroup) view).addView(entryButton,1);
