方法一
1.放在drawable下的selector.xml文件
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true" android:drawable="@drawable/temp1" /> <item android:state_pressed="false" android:state_focused="false" android:drawable="@drawable/temp2" /> <item android:state_focused="true" android:drawable="@drawable/temp3" /> <item android:state_focused="false" android:drawable="@drawable/temp4" /> </selector>
2.布局文件main.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> <Button android:drawableTop="@drawable/shouru" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/button" android:background="@drawable/selector"/> </LinearLayout>
3.只是为了测试,所以效果不是很好,Button部分状态效果图如下:
①初始化的时候默认显示的按钮效果:
②点击后释放显示的效果
③点击不放时的效果
方法二
1.布局文件main.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> <Button android:id="@+id/button" android:drawableTop="@drawable/shouru" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/button" android:background="@drawable/temp4"/> </LinearLayout>
2.主要的java代码,实现点击效果:
Button button = (Button) this.findViewById(R.id.button); button.setOnTouchListener(new Button.OnTouchListener(){ @Override public boolean onTouch(View v, MotionEvent event) { if(event.getAction() == MotionEvent.ACTION_DOWN){ v.setBackgroundResource(R.drawable.temp1); Log.i("TestAndroid Button", "MotionEvent.ACTION_DOWN"); } else if(event.getAction() == MotionEvent.ACTION_UP){ v.setBackgroundResource(R.drawable.temp2); Log.i("TestAndroid Button", "MotionEvent.ACTION_UP"); } return false; } });
