小编Rag*_*dan的帖子

我有一个字符串.该字符串是"New England 12 Philidelphia 24(Final)".我需要一个regaular表达式,我应该能够检索像这样的项目.

1. 第一队 - 新英格兰队
2. 第一队得分--12
3. 第二队 - Philidelpia
4. 第二队得分--24
5. 结果 - 最后或大括号中的任何内容.

我希望得到帮助.函数调用onMeasure我的问题.在My xml中有一个文件(RelativeLayput) - 3个元素:TextView,RelativeLayout并将它们包含在我的类中.现在我的主Activity类和我的创建类

  public class MainActivity extends Activity implements OnTouchListener {

    final String LOG_TAG = "myLogs";
    TextView tv1;
UiMyClass uimc;

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    tv1 = (TextView) findViewById(R.id.mytext2);
    tv1.setOnTouchListener(this);
    String str1 = "qwertyy";
    uimc = (UiMyClass) findViewById(R.id.myclass1);
    Log.d(LOG_TAG, "Open1-0" + "   " + str1);       
}

@Override
public boolean onTouch(View v, MotionEvent event) {
    int evX = (int) event.getX();
    int evY = (int) event.getY();
    switch (event.getAction()) {
    case MotionEvent.ACTION_DOWN:
        tv1.setText("uyq8qyw");
        break;
    case MotionEvent.ACTION_MOVE:
        break;
    case MotionEvent.ACTION_UP: …

我在谷歌搜索但我无法得到它.我需要这种类型,其中值在标记中

我无法理解如何像上面显示的那样做.

GoogleMap gm;

    gm = ((SupportMapFragment) (getSupportFragmentManager()
                .findFragmentById(R.id.map))).getMap();

    gm.setOnInfoWindowClickListener(this);
    gm.addMarker(new MarkerOptions()
                            .title(jsonObj.getString("project_name"));

   @Override
   public void onInfoWindowClick(final Marker marker) {

   String name = marker.getTitle(); // this displays when marker window gets tap

}

但是当我点击标记窗口时,上面的代码就会显示出来.我只想显示上面的iamge链接.怎么做.请帮忙解决问题.

提前致谢.

我只是在滚动浏览带有分页的GridView/ListView加载图像时,由于Aquery库在Android 4.4 Kitkat上延迟加载图像而出现问题.

我想在Android 2.3中使用Action bar和Fragment,但是有一个错误

Type mismatch: cannot convert from android.app.ActionBar to android.support.v7.app.ActionBar

在这一排

final ActionBar bar = getActionBar();

我已经导入了android.support.v4和v7.

package com.hmkcode.android;

import android.support.v7.app.ActionBar;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.view.Menu;
import android.view.MenuItem;


public class MainActivity extends FragmentActivity {
private ViewPager pager;
private TabsAdapter mTabsAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    pager = new ViewPager(this);
    pager.setId(R.id.pager);
    setContentView(pager);

    final ActionBar bar = getActionBar();
    bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

    mTabsAdapter = new TabsAdapter(this, pager);
    mTabsAdapter.addTab(bar.newTab().setText("List Fragment 1"), List_View.class, null);
    mTabsAdapter.addTab(bar.newTab().setText("List Fragment 2"), List_View.class, null);
    mTabsAdapter.addTab(bar.newTab().setText("List …

我在values-v11文件夹中应用了以下代码

styles.xml

 <style name="actionBarTheme" parent="android:Theme.Holo.Light">
    <item name="android:actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>
 </style>

 <style name="MyActionButtonOverflow" parent="@android:style/Widget.Holo.Light.ActionButton.Overflow">
    <item name="android:src">@drawable/action_item_btn</item>
 </style>

但它没有改变溢出图标,这个主题中的所有其他项目工作正常但不是这一个,我错过了什么？

当我点击MyLocation-Button显示Toast时,我想这样做.我试试这段代码:

public void setMyLocationLayerEnabled(View v) {
    Toast toast = Toast.makeText(getApplicationContext(), "Example de Message for Android", Toast.LENGTH_SHORT);
    toast.show();
}

但没有工作.我希望你们中的某些人可以帮助我!

如何在Android中读取和写入可移动SD卡的文件？

我想将Android Id存储在文本文件中.应在外部SD卡上创建文本文件.

码:

PackageManager m = getPackageManager();
String s = getPackageName();
PackageInfo p = m.getPackageInfo(s, 0);
s = p.applicationInfo.dataDir;
File myFile = new File(s + "/MyDoople.txt");
myFile.createNewFile();
FileOutputStream fOut = new FileOutputStream(myFile);
OutputStreamWriter myOutWriter = new OutputStreamWriter(fOut);
myOutWriter.append(TxtS.getText());
myOutWriter.close();
fOut.close();
Toast.makeText(getBaseContext(),"Text Updated",Toast.LENGTH_SHORT).show();

第二是

 File sdCard = new File("file:///mnt/external_sd/");
 File myFile = new File(sdCard, "test.txt");
 FileWriter writer = new FileWriter(myFile); 
 writer.append(TESTSTRING);
 writer.flush(); 
 writer.close();

当我运行我的代码时,我收到此错误:

  : E/InputEventReceiver(1363): Exception dispatching input event.

  : E/MessageQueue-JNI(1363): Exception in MessageQueue callback: handleReceiveCallback

  : D/dalvikvm(1363): GC_CONCURRENT freed 1898K, 30% free 4921K/6992K, paused 78ms+107ms, total 413ms

  : E/MessageQueue-JNI(1363):at  com.example.ikmantest2.MainActivity$6.onItemClick(MainActivity.java:269)

这是我得到错误的代码:

gallery.setOnItemClickListener(new OnItemClickListener(){

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            final Dialog dialog = new Dialog(getBaseContext());
            dialog.setContentView(R.layout.image_dialog_layout);


            // set the custom dialog components - text, image and button
            imageView=(ImageView)dialog.findViewById(R.id.bigger_image);
            imageView.setImageBitmap(exListAdapter.getImageByPosition(lastClickedGroup, arg2)); …

我对有关默认构造函数的错误消息感到困惑.

我有2个MainActivity和ResultDialog.MainActivity创建新对话框并将2strings传递给自定义构造函数的一些方法ResultDialog.

ResultDialog延伸DialogFragment.所以我定义了自己的构造函数,但是当出现错误时我刚刚创建了一个无参数的构造函数,但仍然不允许这样做.

我已经在SO上搜索了abit,但答案有点解释屏幕旋转可能会破坏并使用默认构造函数重新创建屏幕,但仍然无法回答我如何解决这个问题.

错误是避免片段中的非默认构造函数:使用默认构造函数加上Fragment #setArguments(Bundle)

有人请帮助我,我有点困惑.我ResultDialog班级的一部分:

  public class ResultDialog extends DialogFragment {

private String message;//to hold the message to be displayed
private String title;//for alert dialog title

//constructor for the dialog passing along message to be displayed in the alert dialog
public ResultDialog(String message,String title){
    this.message = message;
    this.title = title;

}

public ResultDialog(){
    //default constructor
}
