本文实例为大家分享了Android中PopupWindow弹出式窗口使用的具体代码,供大家参考,具体内容如下
效果图如下:
实现代码如下:
activity_popup_window.xml按钮
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context=".PopupWindowActivity"> <Button android:id="@+id/btn_popupWindow" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:text="PopupWindow" /> </LinearLayout>
自定义弹出的视图layout_pop.xml,也可以用RecycleView或者ListView
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView android:id="@+id/tv_good" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:paddingTop="8dp" android:paddingBottom="8dp" android:text="好" android:textColor="@color/gray" android:textSize="20sp" /> <View android:layout_width="match_parent" android:layout_height="0.5dp" android:background="@color/gray" /> <TextView android:id="@+id/tv_not_too_bad" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:paddingTop="8dp" android:paddingBottom="8dp" android:text="还行" android:textColor="@color/gray" android:textSize="20sp" /> <View android:layout_width="match_parent" android:layout_height="0.5dp" android:background="@color/gray" /> <TextView android:id="@+id/tv_bad" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:paddingTop="8dp" android:paddingBottom="8dp" android:text="不好" android:textColor="@color/gray" android:textSize="20sp" /> </LinearLayout>
PopupWindowActivity类实现代码如下:
public class PopupWindowActivity extends AppCompatActivity { private Button btn_popupWindow; private PopupWindow popupWindow; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_popup_window); btn_popupWindow = findViewById(R.id.btn_popupWindow); btn_popupWindow.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { View popup_view = LayoutInflater.from(PopupWindowActivity.this).inflate(R.layout.layout_pop, null); TextView textView = popup_view.findViewById(R.id.tv_good); textView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { popupWindow.dismiss(); Toast.makeText(PopupWindowActivity.this, "好", Toast.LENGTH_SHORT).show(); } }); popupWindow = new PopupWindow(popup_view, btn_popupWindow.getWidth(), ViewGroup.LayoutParams.WRAP_CONTENT); //设置弹出窗口应该接收外部触摸事件 popupWindow.setOutsideTouchable(true); //设置可聚焦 popupWindow.setFocusable(true); popupWindow.showAsDropDown(btn_popupWindow); } }); } }
以上就是PopupWindow弹出式窗口的简单使用。
