How to set Radiobutton's text below image in Java

问题

我的问题非常简单。我目前有类似这样的单选按钮：
如何在Java中将单选按钮（Radiobutton）的文本设置在图像下方

我想将文本设置为图像下方（并在按钮被点击时将其设置为粗体）。

我的 XML 文件如下：

  1. <HorizontalScrollView
  2.         android:layout_width="wrap_content"
  3.         android:layout_height="wrap_content">
  5.         <RadioGroup
  6.             android:id="@+id/radio_group_category"
  7.             android:layout_width="wrap_content"
  8.             android:layout_height="wrap_content"
  9.             android:orientation="horizontal"/>
  11. </HorizontalScrollView>

我 Java 代码的一部分如下：

  1. RadioGroup categoryGroup = view.findViewById(R.id.radio_group_category);
  3. for(int i=0; i<categories.size(); i++) {
  4.     final String name = categories.get(i).name;
  5.     final int resource = categories.get(i).resource;
  7.     final RadioButton button = new RadioButton(getContext());
  8.     button.setButtonDrawable(resource);
  9.     button.setText(name);
  10.     button.setOnClickListener(new View.OnClickListener() {
  11.         @Override
  12.         public void onClick(View view) {
  13.             // 设置文本为粗体（我还会添加一些逻辑）
  14.         }
  15.     });
  17.     categoryGroup.addView(button);
  18. }

My question is fairly simple. I currently have Radiobuttons that look like this :
如何在Java中将单选按钮（Radiobutton）的文本设置在图像下方

I would like to set the text to be below the image (and eventually set it as bold when the button is clicked).

My XML file looks like this :

  1. &lt;HorizontalScrollView
  2.         android:layout_width=&quot;wrap_content&quot;
  3.         android:layout_height=&quot;wrap_content&quot;&gt;
  5.         &lt;RadioGroup
  6.             android:id=&quot;@+id/radio_group_category&quot;
  7.             android:layout_width=&quot;wrap_content&quot;
  8.             android:layout_height=&quot;wrap_content&quot;
  9.             android:orientation=&quot;horizontal&quot;/&gt;
  11. &lt;/HorizontalScrollView&gt;

And part of my Java code :

  1. RadioGroup categoryGroup = view.findViewById(R.id.radio_group_category);
  3.         for(int i=0; i&lt;categories.size(); i++) {
  4.             final String name = categories.get(i).name;
  5.             final int resource = categories.get(i).resource;
  7.             final RadioButton button = new RadioButton(getContext());
  8.             button.setButtonDrawable(resource);
  9.             button.setText(name);
  10.             button.setOnClickListener(new View.OnClickListener() {
  11.                 @Override
  12.                 public void onClick(View view) {
  13.                     //Set text as bold (I&#39;ll add some logic too)
  14.                 }
  15.             });
  17.             categoryGroup.addView(button);
  18.         }

尝试一下这个代码：

  1. public class MainActivity extends AppCompatActivity {
  3.     LinearLayout linearLayout;
  4.     RadioGroup radioGroup;
  5.     RadioButton radioButton;
  7.     @Override
  8.     protected void onCreate(Bundle savedInstanceState) {
  9.         super.onCreate(savedInstanceState);
  10.         // setContentView(R.layout.activity_main);
  12.         linearLayout = new LinearLayout(getApplicationContext());
  13.         LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
  14.                 LinearLayout.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
  15.         radioGroup = new RadioGroup(getApplicationContext());
  16.         linearLayout.addView(radioGroup);
  18.         for (int i = 0; i < 5; i++) {
  19.             radioButton = new RadioButton(getApplicationContext());
  20.             radioButton.setText(String.valueOf(i));
  21.             radioGroup.addView(radioButton);
  22.         }
  24.         LinearLayout.LayoutParams params1 = new LinearLayout.LayoutParams(
  25.                 ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
  26.         params1.setMargins(3, 0, 3, 5);
  27.         getWindow().addContentView(linearLayout, params1);
  28.     }
  29. }

这段代码对我有效，看看这个效果：

这就是它的外观：

  13.     LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
  14.             LinearLayout.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
  15.     radioGroup = new RadioGroup(getApplicationContext());
  16.     linearLayout.addView(radioGroup);
  18.     for (int i = 0; i&lt;5 ;i++){
  19.         radioButton = new RadioButton(getApplicationContext());
  20.         radioButton.setText(String.valueOf(i));
  21.         radioGroup.addView(radioButton);
  22.     }
  26.     LinearLayout.LayoutParams params1 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
  27.     params1.setMargins(3, 0, 3, 5);
  28.     getWindow().addContentView(linearLayout, params1);
  31.   }
  32. }

尝试这个：

  1. RadioGroup categoryGroup = view.findViewById(R.id.radio_group_category);
  3. for (int i = 0; i < categories.size(); i++) {
  4.     final String name = categories.get(i).name;
  5.     final int resource = categories.get(i).resource;
  7.     final RadioButton button = new RadioButton(getContext());
  8.     Drawable drawable = getResources().getDrawable(resource);
  9.     button.setCompoundDrawablesWithIntrinsicBounds(null, drawable, null, null);
  10.     button.setButtonDrawable(null);
  11.     button.setText(name);
  12.     button.setOnClickListener(new View.OnClickListener() {
  13.         @Override
  14.         public void onClick(View view) {
  15.             if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
  16.                 button.setText(Html.fromHtml("<h2>" + button.getText().toString() + "</h2>",
  17.                         Html.FROM_HTML_MODE_COMPACT));

  20.             }
  21.         }
  22.     });
  24.     categoryGroup.addView(button);
