<4> 自定义菜单栏
pop的布局：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#6e6e6e" android:orientation="vertical"> <TextView android:id="@+id/textView1" android:layout_width="140dp" android:layout_height="40dp" android:drawableLeft="@mipmap/yun" android:gravity="center_horizontal|center_vertical" android:text="菜单" android:textColor="#000000" android:textSize="17sp" /> <TextView android:id="@+id/textView2" android:layout_width="140dp" android:layout_height="40dp" android:drawableLeft="@mipmap/yun" android:gravity="center_horizontal|center_vertical" android:text="收藏" android:textColor="#000000" android:textSize="17sp" /> <TextView android:id="@+id/textView3" android:layout_width="140dp" android:layout_height="40dp" android:drawableLeft="@mipmap/yun" android:gravity="center_horizontal|center_vertical" android:text="爱好" android:textColor="#000000" android:textSize="17sp" /> </LinearLayout>
方法实现：
/**
*
* @param view view点击事件，弹出popupwindow，view传入作为参数
*/
private void showPopupWindow_dingbu(View view) {
/**
* 一个自定义的布局，作为显示的内容
*/
View contentView = LayoutInflater.from(MainActivity.this).inflate(R.layout.pop_layout, null);
final PopupWindow popupWindow = new PopupWindow(contentView,
LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, true);
WindowManager manager=(WindowManager) getSystemService(Context.WINDOW_SERVICE);
popupWindow.setTouchable(true);
popupWindow.setBackgroundDrawable(new BitmapDrawable());
popupWindow.setOutsideTouchable(true);
int xpos=manager.getDefaultDisplay().getWidth()/2-popupWindow.getWidth()/2;
TextView textView3 = (TextView) contentView.findViewById(R.id.textView1);
/**
* 设置按钮的点击事件
*/
textView3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this,"ok",Toast.LENGTH_SHORT).show();
popupWindow.dismiss();
}
});
popupWindow.setTouchInterceptor(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
return false;
// 这里如果返回true的话，touch事件将被拦截
// 拦截后 PopupWindow的onTouchEvent不被调用，这样点击外部区域无法dismiss
}
});
popupWindow.showAtLocation(view, Gravity.TOP|Gravity.RIGHT, 0, 140); //右下
popupWindow.showAsDropDown(view);
}
