android 控件使用集锦

layout.xml

<RadioGroup android:id="@+id/sex" style="@style/textInfo" android><RadioButton android:text="男：" android:id="@+id/radionBtn_man" ></RadioButton><RadioButton android:text="女：" android:id="@+id/radionBtn_woman" ></RadioButton></RadioGroup>
?

RadioButton rb = (RadioButton) findViewById(sexRadioGroup.getCheckedRadioButtonId());mUser.setSex(((RadioButton) findViewById(sexRadioGroup.getCheckedRadioButtonId())).getText().toString());
?

?

<RadioGroup android:id="@+id/sex" style="@style/textInfo" android:orientation="vertical">

其中的android:orientation="vertical" 是设置group中的布局水平还是垂直，默认是垂直
android:checked="true" 标示默认选中

ps:如果多个radiobutton都有android:checked="true"，则选中最后一个mTempPath.moveTo(50, 200);
mTempPath.quadTo(52, 10, 60, 200);
mTempPath.close();mTempPath.setFillType(FillType.EVEN_ODD);

mPaint.setStyle(Style.FILL);
mCanvas.drawPath(mTempPath, mPaint);</pre>
<p>?填充<span style="white-space: pre;">close()之后自动把path路径封闭了</span></p>
<p>?</p>
