项目中需要在某一页实现底部弹出框，于是结合了网上的底部弹出框，自己做了个弹出窗，有点难看，可以根据自己的需要更具体的美化
效果图：
接下来，我们来实现此功能：
直接上代码吧！
1、在点击某个按钮，进行触发，弹出底部框
/**
* 创建popupWindow
* popupWindow 是全局定义的，根据自己需要惊醒定义* @param view View 比如：btn_ok的点击后触发popupWindow，则view就是id为 btn_ok对应的view
*/
private void bottomwindow(View view) {
if (popupWindow != null && popupWindow.isShowing()) {
return;
}
LinearLayout layout = (LinearLayout) getLayoutInflater().inflate(R.layout.pop_five_activity_bottom_layout, null);
popupWindow = new PopupWindow(layout,
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
//点击空白处时，隐藏掉pop窗口
popupWindow.setFocusable(true);
popupWindow.setBackgroundDrawable(new BitmapDrawable());
//添加弹出、弹入的动画
// popupWindow.setAnimationStyle(R.style.Popupwindow);
int[] location = new int[2];
view.getLocationOnScreen(location);
popupWindow.showAtLocation(view, Gravity.LEFT | Gravity.BOTTOM, 0, -location[1]);
//添加按键事件监听
setButtonListeners(layout);
//添加pop窗口关闭事件，主要是实现关闭时改变背景的透明度
// popupWindow.setOnDismissListener(new poponDismissListener());
// backgroundAlpha(1f);
}
/**
* 设置popupWindow布局中按钮的点击事件
* p* @param view View
*/
private void setButtonListeners(LinearLayout layout) {
Button btn_cancel = (Button) layout.findViewById(R.id.btn_cancel);
Button btn_ok = (Button) layout.findViewById(R.id.btn_ok);
final EditText et_lat = layout.findViewById(R.id.et_lat);
final EditText et_lng = layout.findViewById(R.id.et_lng);
final TextView tv_showResult = layout.findViewById(R.id.tv_showResult);
btn_cancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (popupWindow != null && popupWindow.isShowing()) {
//在此处添加你的按键处理 xxx
popupWindow.dismiss();
}
}
});
btn_ok.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (popupWindow != null && popupWindow.isShowing()) {
//在此处添加你的按键处理 xxx
String lat = et_lat.getText().toString().trim();
String lng = et_lng.getText().toString().trim();
if (TextUtils.isEmpty(lat) || TextUtils.isEmpty(lng)) {
Toast.makeText(FiveActivity.this, "请填写经纬度", Toast.LENGTH_SHORT).show();
} else {
long startTime = System.currentTimeMillis();
Log.i("startTime:", startTime + "");
Double resultDistance = 0.0;
Double distance;
LatLng startPoint = new LatLng(Double.parseDouble(lat), Double.parseDouble(lng));
List<LatLngDB> latLngDBList = DataSupport.findAll(LatLngDB.class);
int i = 0;
for (LatLngDB latLngDB : latLngDBList) {
Log.i("次数:", "" + i);
i++;
//计算p1、p2两点之间的直线距离，单位：米
LatLng endPoint = new LatLng(latLngDB.getLat(), latLngDB.getLng());
distance = DistanceUtil.getDistance(startPoint, endPoint);
Log.i("距离:", "" + distance);
if (resultDistance < distance) {
resultDistance = distance;
}
}
long endTime = System.currentTimeMillis();
Log.i("endTime:", endTime + "");
long timeCha = endTime - startTime;
Toast.makeText(FiveActivity.this, "---" + timeCha + "ms", Toast.LENGTH_SHORT).show();
int minute = (int) (timeCha / 60) % 60;
int second = (int) (timeCha % 60);
if (minute < 10 && second < 10) {
tv_showResult.setText("用时 0" + minute + ":0" + second + ";最远距离:" + resultDistance);
} else if (minute < 10 && second >= 10) {
tv_showResult.setText("用时 0" + minute + ":" + second + ";最远距离:" + resultDistance);
} else if (minute >= 10 && second < 10) {
tv_showResult.setText("用时 " + minute + ":0" + second + ";最远距离:" + resultDistance);
} else if (minute >= 10 && second >= 10) {
tv_showResult.setText("用时 " + minute + ":" + second + ";最远距离:" + resultDistance);
}
}
}
}
});
}
2、pop_five_activity_bottom_layout xml布局文件
<?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:background="@drawable/pop_view_bg"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="@+id/btn_cancel"
android:layout_width="wrap_content"
android:layout_height="@dimen/view_height_25"
android:layout_margin="@dimen/margin_5"
android:background="@drawable/pop_add_sub_good_cancel_bg"
android:text="取消"
android:textColor="@color/red"
android:textSize="@dimen/fontsize_12" />
<View
android:layout_width="0dp"
android:layout_height="@dimen/view_height_25"
android:layout_weight="1" />
<Button
android:id="@+id/btn_ok"
android:layout_width="wrap_content"
android:layout_height="@dimen/view_height_25"
android:layout_margin="@dimen/margin_5"
android:background="@drawable/pop_add_sub_good_cancel_bg"
android:text="确定"
android:textColor="@color/red"
android:textSize="@dimen/fontsize_12" />
</LinearLayout>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_margin="@dimen/margin_5"
android:background="@drawable/pop_view_bg" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="@dimen/margin_10">
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:text="(" />
<EditText
android:id="@+id/et_lng"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="bottom"
android:hint="经度值" />
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="bottom"
android:text="," />
<EditText
android:id="@+id/et_lat"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="bottom"
android:hint="纬度值" />
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:text=")" />
</LinearLayout>
<TextView
android:id="@+id/tv_showResult"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="@dimen/margin_10"
android:textColor="@color/black"
android:textStyle="bold" />
</LinearLayout>
3、pop_view_bg 资源文件，在res文件 > 右击 > new > Android resource file > Resource Type 选择 Drawable
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="0.5dp"
android:color="@color/red"
android:dashGap="2dp"
android:dashWidth="4dp" />
<solid android:color="#F0F0F0" />
</shape>
4、pop_add_sub_good_cancel_bg 资源文件，步骤同 3
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="@color/white" />
<stroke
android:width="1dp"
android:color="@color/red" />
<corners android:radius="2dp" />
</shape>
5、pop_view_bg 资源文件，步骤同 3
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="0.5dp"
android:color="@color/red"
android:dashGap="2dp"
android:dashWidth="4dp" />
<solid android:color="#F0F0F0" />
</shape>
