<>Button
继承TextView
*
<>文字大小、颜色
*
控件布局文件:
* <Button android:textSize="24sp" android:textColor="#a00de4"
android:background="#cfb0c8"/>
*
或者在shepe布局中(后面会讲到怎么创建shepe布局文件)
* <solid android:color="#ff5960"/>
*
<>自定义背景形状
*
首先在res/drawable文件夹下,新建一个Drawble resource file,类型为shepe,命名为:shape_1.xml
*
android:radius:定义四个角的的圆角半径。
*
控件布局引用:
<Button android:background="@drawable/shape_1"/>
*
shepe布局:
* <corners android:radius="20dp"/>
*
<>自定义按压效果
*
首先在res/drawable文件夹下,新建一个Drawble resource file,类型为selector,命名为:sel__bnt1.xml
*
控件布局引用:
* android:background="@drawable/sel__bnt1"
*
selector布局:
* //按压时 <item android:state_pressed="true"> <shape> <solid android:color="
#FF9977"></solid> <corners android:radius="60dp"></corners> </shape> </item>
//不按压时<item android:state_pressed="false"> <shape> <solid android:color="#CC7">
</solid> <corners android:radius="60dp"></corners> </shape> </item>
*
<>点击事件
*
通过创建一个方法,然后在控件布局中调用这个方法
*
* 在Activity中创建
* public void showToast(View view){ Toast.makeText(this,"不要点我了!",Toast.
LENGTH_SHORT).show(); }
*
在控件布局中调用
* <Button android:onClick="showToast" />
*
* Activity直接声明,然后在方法中添加点击反应
* private Button mBtn4; mBtn4 = findViewById(R.id.btn_4);
mBtn4.setOnClickListener(new View.OnClickListener() { @Override public void
onClick(View view) {
Toast.makeText(Activity3.this,"你点下面那个按钮",Toast.LENGTH_SHORT).show(); } });
