在Android中设置单选按钮的位置可以通过布局文件或者代码实现。
示例代码:
<RadioGroup
android:id="@+id/radioGroup"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<RadioButton
android:id="@+id/radioButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Option 1"
android:layout_gravity="start" />
<RadioButton
android:id="@+id/radioButton2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Option 2"
android:layout_gravity="center" />
<RadioButton
android:id="@+id/radioButton3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Option 3"
android:layout_gravity="end" />
</RadioGroup>
示例代码:
RadioGroup radioGroup = findViewById(R.id.radioGroup);
RadioButton radioButton1 = new RadioButton(this);
radioButton1.setText("Option 1");
RadioGroup.LayoutParams layoutParams1 = new RadioGroup.LayoutParams(
RadioGroup.LayoutParams.WRAP_CONTENT,
RadioGroup.LayoutParams.WRAP_CONTENT
);
layoutParams1.gravity = Gravity.START;
radioButton1.setLayoutParams(layoutParams1);
radioGroup.addView(radioButton1);
RadioButton radioButton2 = new RadioButton(this);
radioButton2.setText("Option 2");
RadioGroup.LayoutParams layoutParams2 = new RadioGroup.LayoutParams(
RadioGroup.LayoutParams.WRAP_CONTENT,
RadioGroup.LayoutParams.WRAP_CONTENT
);
layoutParams2.gravity = Gravity.CENTER;
radioButton2.setLayoutParams(layoutParams2);
radioGroup.addView(radioButton2);
RadioButton radioButton3 = new RadioButton(this);
radioButton3.setText("Option 3");
RadioGroup.LayoutParams layoutParams3 = new RadioGroup.LayoutParams(
RadioGroup.LayoutParams.WRAP_CONTENT,
RadioGroup.LayoutParams.WRAP_CONTENT
);
layoutParams3.gravity = Gravity.END;
radioButton3.setLayoutParams(layoutParams3);
radioGroup.addView(radioButton3);
