问题描述
在我的活动有一个切换按钮。我希望每一次更改切换按钮,不选中对话框出现,当你是preSS的消息公布在Facebook的墙壁上。
我拿了code在Facebook上发布没有Facebook的对话框这里
下面是我的code:
OnCheckedChangeListener toggleButtonListener =新OnCheckedChangeListener(){
//调用时用户切换会话状态
@覆盖
公共无效onCheckedChanged(CompoundButton buttonView,
布尔器isChecked){
如果(!器isChecked){
AlertDialog.Builder建设者=新AlertDialog.Builder(
SocialFootActivity.this);
builder.setMessage(
你想在Facebook上共享)
.setCancelable(假)
.setPositiveButton(是,
新DialogInterface.OnClickListener(){
公共无效的onClick(DialogInterface对话框,
INT ID){
SocialFootActivity.this.runOnUiThread(新的Runnable(){
@覆盖
公共无效的run(){
新PostMsg()执行(的Hello World);
}});
}
})
.setNegativeButton(否,
新DialogInterface.OnClickListener(){
公共无效的onClick(DialogInterface对话框,
INT ID){
dialog.cancel();
}
});
AlertDialog警报= builder.create();
alert.show(); }其他{
//做出头
}
}
};
的AsyncTask
公共类PostMsg扩展的AsyncTask<弦乐,太虚,太虚> {@覆盖
保护无效doInBackground(字符串...味精){
// TODO自动生成方法存根
尝试{
SocialFootActivity SF =新SocialFootActivity();
字符串的响应= sf.facebook.request(我);
捆绑参数=新包();
parameters.putString(信息,味精[0]);
parameters.putString(说明,测试测试测试);
响应= sf.facebook.request(ME /饲料,参数,POST);
Log.d(测试,得到了回应:+响应);
如果(响应==空|| response.equals()
|| response.equals(假)){
Log.v(错误,空白响应);
}
}赶上(例外五){
e.printStackTrace();
}
返回null;
}}

有一个错误在这行你code的:
SocialFootActivity.this.runOnUiThread(新的Runnable(){
@覆盖
公共无效的run(){
新PostMsg()执行(的Hello World);
}});
为什么你想运行一个的AsyncTask
使用 runOnUiThread()
?
您是假设简单地调用的AsyncTask
在这样的的OnClick()
方法:
OnCheckedChangeListener toggleButtonListener =新OnCheckedChangeListener(){
//调用时用户切换会话状态
@覆盖
公共无效onCheckedChanged(CompoundButton buttonView,
布尔器isChecked){
如果(!器isChecked){
AlertDialog.Builder建设者=新AlertDialog.Builder(
SocialFootActivity.this);
builder.setMessage(
你想在Facebook上共享)
.setCancelable(假)
.setPositiveButton(是,
新DialogInterface.OnClickListener(){
公共无效的onClick(DialogInterface对话框,
INT ID){ 新PostMsg()执行(的Hello World);
});
}
然后显示一个 progressdialog
在上preExecute()
你的 AsyncTask的
将在UI线程中显示,而你的 doInBackground()
会发生在后台非UI线程。
In my activity there is a toggle button. I want every time you change the toggle button to unchecked a dialog box appear and when you press on Yes a message is published on the facebook's wall.
I took code for publishing on facebook without facebook's dialog here http://stackoverflow.com/a/4376415/1403979
Here is my code:
OnCheckedChangeListener toggleButtonListener = new OnCheckedChangeListener() {
// called when user toggles session state
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
if (!isChecked) {
AlertDialog.Builder builder = new AlertDialog.Builder(
SocialFootActivity.this);
builder.setMessage(
"Do you want to share on facebook")
.setCancelable(false)
.setPositiveButton("Yes",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
SocialFootActivity.this.runOnUiThread(new Runnable() {
@Override
public void run() {
new PostMsg().execute("Hello World");
}});
}
})
.setNegativeButton("No",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
} else {
//do somethings
}
}
};
AsyncTask
public class PostMsg extends AsyncTask<String,Void,Void>{
@Override
protected Void doInBackground(String... msg) {
// TODO Auto-generated method stub
try {
SocialFootActivity sf = new SocialFootActivity();
String response = sf.facebook.request("me");
Bundle parameters = new Bundle();
parameters.putString("message", msg[0]);
parameters.putString("description", "test test test");
response = sf.facebook.request("me/feed", parameters, "POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("")
|| response.equals("false")) {
Log.v("Error", "Blank response");
}
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}

There is an error in this line of your code:
SocialFootActivity.this.runOnUiThread(new Runnable() {
@Override
public void run() {
new PostMsg().execute("Hello World");
}});
Why are you trying to run a AsyncTask
using the runOnUiThread()
?
You are suppose to simply call the AsyncTask
in the OnClick()
method like this:
OnCheckedChangeListener toggleButtonListener = new OnCheckedChangeListener() {
// called when user toggles session state
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
if (!isChecked) {
AlertDialog.Builder builder = new AlertDialog.Builder(
SocialFootActivity.this);
builder.setMessage(
"Do you want to share on facebook")
.setCancelable(false)
.setPositiveButton("Yes",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
new PostMsg().execute("Hello World");
});
}
Then show a progressdialog
in the onPreExecute()
of your AsyncTask
which will be shown on the UI-Thread while your doInBackground()
will happen in the background non-UI thread.
这篇关于一个对话框,里面的AsyncTask - 内螺纹无法创建处理已经不叫尺蠖prepare()。的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
