我想创建，通知有关启用在手机上的GPS会降低电池的使用寿命，用户提示对话框。我希望它弹出，但有一个复选框，上面写着：不要再问我。

感谢您，
Zukky。
AlertDialog.Builder提示=新AlertDialog.Builder（本）;
prompt.setCancelable（假）;
prompt.setTitle（警告）;
prompt.setMessage（提示：否则，它会使用网络寻找+
您的位置。这是不准确的，但节省了+
电池！切换GPS上更好的准确性+
但请记住，它使用更多的电池！）;
解决方案
它集机器人preferences并检查它是否将显示对话框或没有价值。
checkbox.xml 资源/布局
＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT; LinearLayout中的xmlns：机器人=http://schemas.android.com/apk/res/android
机器人：ID =@ + ID / layout_root
机器人：layout_width =FILL_PARENT
机器人：layout_height =FILL_PARENT
机器人：方向=横向
机器人：填充=10dp＆GT;
＆LT;复选框
的xmlns：机器人=http://schemas.android.com/apk/res/android
机器人：ID =@ + ID /跳过
机器人：layout_width =WRAP_CONTENT
机器人：layout_height =WRAP_CONTENT
机器人：文本=好了，请不要再显示。 ＆GT;
＆LT; /复选框＆GT;
＆LT; / LinearLayout中＆GT;
Activity.java
公共类SeActivity延伸活动{
公共静态最后弦乐preFS_NAME =我的prefsFile1;
公开复选框dontShowAgain;
/ **第一次创建活动时调用。 * /
@覆盖
公共无效的onCreate（包savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.main）;
}
/ **当活动被带到前面调用。 * /
@覆盖
保护无效onResume（）{
AlertDialog.Builder ADB =新AlertDialog.Builder（本）;
LayoutInflater adbInflater = LayoutInflater.from（本）;
查看eulaLayout = adbInflater.inflate（R.layout.checkbox，NULL）;
dontShowAgain =（复选框）eulaLayout.findViewById（R.id.skip）;
adb.setView（eulaLayout）;
adb.setTitle（注意）;
adb.setMessage（Html.fromHtml（Zukky，我怎么能看到这个呢？））;
adb.setPositiveButton（OK，新DialogInterface.OnClickListener（）{
公共无效的onClick（DialogInterface对话，诠释它）{
字符串checkBoxResult =未选中
如果（dontShowAgain.isChecked（））
checkBoxResult =检查;
共享preferences设置= getShared preferences（preFS_NAME，0）;
共享preferences.Editor编辑器= settings.edit（）;
editor.putString（skipMessage，checkBoxResult）;
//提交的修改！
editor.commit（）;
startActivity（新意图（Intent.ACTION_VIEW，Uri.parse（http://misha.beshkin.lv/android-alertdialog-with-checkbox/）））;
返回;
}
}）;
adb.setNegativeButton（取消，新DialogInterface.OnClickListener（）{
公共无效的onClick（DialogInterface对话，诠释它）{
字符串checkBoxResult =未选中
如果（dontShowAgain.isChecked（））
checkBoxResult =检查;
共享preferences设置= getShared preferences（preFS_NAME，0）;
共享preferences.Editor编辑器= settings.edit（）;
editor.putString（skipMessage，checkBoxResult）;
//提交的修改！
editor.commit（）;
返回;
}
}）;
共享preferences设置= getShared preferences（preFS_NAME，0）;
字符串skipMessage = settings.getString（skipMessage，未选中）;
如果（！skipMessage.equals（选中））
adb.show（）;
super.onResume（）;
}
}
所以，我做了复制和粘贴了。只更改了消息字符串。它精美的作品。
I am trying to create a "hint" dialog box that informs the user about enabling GPS on their phone will decrease battery life. I want it to pop-up but have a check box that says: "Do not ask me again".
How do I go about creating this in Android?
Thank you,
Zukky.
AlertDialog.Builder prompt = new AlertDialog.Builder(this);
prompt.setCancelable(false);
prompt.setTitle("Warning");
prompt.setMessage ("HINT: Otherwise, it will use network to find" +
"your location. It's inaccurate but saves on " +
"battery! Switch GPS on for better accuracy " +
"but remember it uses more battery!");
解决方案
EDIT: I'm including the code here with reference to the original author's site.
It sets a value in Android Preferences and checks it to whether it will show the dialog or not.
checkbox.xml in resources/layouts
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_root"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:padding="10dp" >
<CheckBox
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/skip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Ok please do not show again." >
</CheckBox>
</LinearLayout>
Activity.java
public class SeActivity extends Activity {
public static final String PREFS_NAME = "MyPrefsFile1";
public CheckBox dontShowAgain;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
/** Called when the activity is brought to front. */
@Override
protected void onResume() {
AlertDialog.Builder adb = new AlertDialog.Builder(this);
LayoutInflater adbInflater = LayoutInflater.from(this);
View eulaLayout = adbInflater.inflate(R.layout.checkbox, null);
dontShowAgain = (CheckBox) eulaLayout.findViewById(R.id.skip);
adb.setView(eulaLayout);
adb.setTitle("Attention");
adb.setMessage(Html.fromHtml("Zukky, how can I see this then?"));
adb.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
String checkBoxResult = "NOT checked";
if (dontShowAgain.isChecked())
checkBoxResult = "checked";
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putString("skipMessage", checkBoxResult);
// Commit the edits!
editor.commit();
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://misha.beshkin.lv/android-alertdialog-with-checkbox/")));
return;
}
});
adb.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
String checkBoxResult = "NOT checked";
if (dontShowAgain.isChecked())
checkBoxResult = "checked";
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putString("skipMessage", checkBoxResult);
// Commit the edits!
editor.commit();
return;
}
});
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
String skipMessage = settings.getString("skipMessage", "NOT checked");
if (!skipMessage.equals("checked"))
adb.show();
super.onResume();
}
}
SO, I did "copy and paste" too. Changed only the message strings. It works beautifully.
