1、新写一个layout文件 作为popupwindow的布局文件
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:gravity="center" android:background="#c0000000"> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" android:gravity="center" android:background="@drawable/popupwindow"> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:layout_margin="5dip"> <TextView android:text="课程：" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <EditText android:id="@+id/popupwindow_class" android:layout_width="200dip" android:layout_height="wrap_content" /> </LinearLayout> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center"> <Button android:text="添加" android:id="@+id/popupwindow_add" android:layout_width="wrap_content" android:layout_height="wrap_content"> </Button> <Button android:text="取消" android:id="@+id/prpupwindow_cancel" android:layout_width="wrap_content" android:layout_height="wrap_content"> </Button> </LinearLayout> </LinearLayout></LinearLayout>
<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <gradient android:startColor="#c0000000" android:endColor="#c0000000" android:angle="90" /><!--背景颜色渐变 --> <stroke android:dashWidth="2dp" android:dashGap="2dp" android:width="2dp" android:color="#FF00ff00"></stroke> <!--描边 --> <corners android:bottomRightRadius="5dp" android:bottomLeftRadius="5dp" android:topLeftRadius="5dp" android:topRightRadius="5dp" /><!--设置圆角--></shape>
<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"> <scale android:interpolator="@android:anim/accelerate_decelerate_interpolator" android:fromXScale="0.0" android:toXScale="1.0" android:fromYScale="0.0" android:toYScale="1.0" android:pivotX="50%" android:pivotY="50%" android:fillAfter="true" android:duration="3000" /> <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="3000" /></set>
/** * 添加课程的popupwindow * @param v */ private void initPopupWindow(View v){ final View view = this.getLayoutInflater().inflate(R.layout.popupwindow, null); popupWindow = new PopupWindow(view, LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT, true); Button btnOK=(Button)view.findViewById(R.id.popupwindow_add); btnOK.setOnClickListener(new OnClickListener(){ public void onClick(View v) { EditText et=(EditText)view.findViewById(R.id.popupwindow_class); 。。。。。。//一些处理 }); //Cancel按钮及其处理事件 Button btnCancel=(Button)view.findViewById(R.id.prpupwindow_cancel); btnCancel.setOnClickListener(new OnClickListener(){ public void onClick(View v) { popupWindow.dismiss();//关闭 } }); popupWindow.setBackgroundDrawable(new BitmapDrawable()); popupWindow.showAtLocation(v, Gravity.CENTER, 0, 0); popupWindow.setAnimationStyle(R.anim.popupwindow); }
