小编use*_*299的帖子

在特殊情况下,我需要从我的活动中删除对话框主题,但它似乎不起作用.这是一个例子

第一项活动:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    startActivity(new Intent(MainActivity.this, SecondActivity.class));
}

第二项活动:

public void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setTheme(android.R.style.Theme);
    setContentView(R.layout.activity_second);
}

清单摘录:

 <activity android:name="SecondActivity" android:theme="@android:style/Theme.Dialog"></activity>

当我运行它仍然是对话主题.

谢谢.

我有一个带有两个editexts的布局.我需要设置第二个焦点,并在第一个点击输入键时进行编辑.我有设置焦点的代码但是当第二个获得焦点时我无法开始输入.

PS我还需要edittext正好一行高,不可能制作附加行.它也有效.pss android 2.3

XML代码:

<EditText
            android:id="@+id/email"
            style="@style/profileLoginInput"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" android:hint="@string/email" android:ems="10" android:lines="1" android:maxLines="1" android:ellipsize="end">

            <requestFocus />
        </EditText>

<EditText
            android:id="@+id/password"
            style="@style/profileLoginInput"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="20dp"
            android:ems="10"
            android:inputType="textPassword" android:hint="@string/password">

Java代码:

((EditText) findViewById(R.id.email)).setOnKeyListener(new OnKeyListener(){
            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event)
            {
                if (event.getAction() == KeyEvent.ACTION_DOWN)
                {
                    switch (keyCode)
                    {
                        case KeyEvent.KEYCODE_DPAD_CENTER:
                        case KeyEvent.KEYCODE_ENTER:
                        ((EditText) findViewById(R.id.password)).requestFocus();
                        return true;
                        default:
                            break;
                    }
                }
                return false;
            }
        });

在我的应用程序中,我需要处理物理按钮事件,例如音量按钮点击.为此,我使用了audiomanager的registerMediaButtonEventReceiver方法.有一篇文章与我的情况有关,虽然我无法让它发挥作用.

这是我正在使用的代码:

public class VolumeBroadcastActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        AudioManager manager = (AudioManager) getSystemService(AUDIO_SERVICE);
        manager.registerMediaButtonEventReceiver(new ComponentName(getPackageName(), RemoteControlReceiver.class.getName()));
    }

    public class RemoteControlReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {

            Toast.makeText(VolumeBroadcastActivity.this, "1",1).show();
            if (Intent.ACTION_MEDIA_BUTTON.equals(intent.getAction())) {
            }
        }
    }
}

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="localhost.volume.broadcast"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="10" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".VolumeBroadcastActivity"
            android:label="@string/app_name" >
            <intent-filter> …

我试图像这样使用setConnectTimeout函数:

protected HttpURLConnection getConnection() throws SocketTimeoutException, IOException{
    Log.d("HTTPRequest", address);
    URL page = new URL(address);
    HttpURLConnection connection = (HttpURLConnection) page.openConnection();

    connection.setUseCaches(cacheResult);
    connection.setConnectTimeout(3000);
    connection.connect();
    return connection;
}

然后:

public String getTextData() throws InternetConnectionUnavailableException {
    try{
        HttpURLConnection conn = getConnection();
        StringBuffer text = new StringBuffer();
        InputStreamReader in = new InputStreamReader((InputStream) conn.getContent());
        BufferedReader buff = new BufferedReader(in);
        String line;

        while (true) {
            if((line = buff.readLine()) != null){
                text.append(line);
            }else{
                break;
            }
        }
        return (text.toString());
    } catch (SocketTimeoutException socketTimeoutException) {
            throw new InternetConnectionUnavailableException();
    } catch …

我用它来获取当前时间戳,以秒为单位并将其添加到字符串Double.toString((System.currentTimeMillis()/1000)) 但是不是十进制表示法,而是"1.23213E9".如何切换到十进制表示法？
