如何使用远程URL在Android模拟器中播放mp4视频？我使用下面的代码,但这段代码给我错误"抱歉,这个视频无法播放".

07-05 16:58:19.525: INFO/AwesomePlayer(34): mConnectingDataSource->connect() returned -1007
07-05 16:58:19.525: ERROR/MediaPlayer(1242): error (1, -1007)
07-05 16:58:19.525: ERROR/MediaPlayer(1242): Error (1,-1007)
07-05 16:58:19.525: DEBUG/VideoView(1242): Error: 1,-1007

我的守则是: -

public class VideoPlayerController extends Activity {
     @Override
     public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.main);          
                VideoView videoView = (VideoView) findViewById(R.id.VideoView);
                MediaController mediaController = new MediaController(this);
                mediaController.setAnchorView(videoView);
                String Video="http://s509.photobucket.com/albums/s338/eveanthony/?action=view&current=Video013.mp4";
                videoView.setMediaController(mediaController);
                videoView.setVideoURI(Uri.parse(Video));
                videoView.start();
            }
}

我有一个按钮,通过意图在我的设备上启动谷歌地图应用程序.我希望能够传递一个生成KML文件的php页面.

我在使用JS中的googlemaps api之前在网站上做过这个 - 但它似乎不适用于Android.

我的php文件如下;

<?php
     echo '<kml xmlns="http://www.google.com/earth/kml/2">';
     echo '<Placemark>';
     echo '<name>Google Inc.</name>';
     echo '<description>1600 Amphitheatre Parkway, Mountain View, CA 94043</description>';
     echo '<Point>';
     echo '<coordinates>-122.0841430, 37.4219720, 0</coordinates>';
     echo '</Point>';
     echo '</Placemark>';
     echo '</kml>';
?>  

启动时间:

final Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("geo:0,0?q=http://website.com/kml_gen.php"));
startActivity(myIntent);

它启动地图,找到文件 - 但不会显示它'因为它包含错误'.

这是不可能的,还是有其他方法来构建可能有用的意图？

如何在按钮的点击事件中将图像存储在sqlite数据库中？

以下代码用于从特定文件夹中获取图像,但如何获取子文件夹的sdcard文件夹图像.

Cursor actualimagecursor = managedQuery(
    MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj,
    MediaStore.Images.Media.DATA + " like ? ",
    new String[] { "%unzipped%" }, null);

对不起英语沟通不好.

我正在研究一个ANdroid应用程序.在我的应用程序中,我必须列出所有的对话,我做了那个部分.每个对话都包含该号码的所有短信.因此我必须对所有短信的收件箱和sentsms进行鉴别.我知道以下api可用于查找收件箱并发送.

content://sms/inbox
content://sms/sent

但我不想使用它.我使用api列出了所有的短信

content://sms/

我测试了columnindex的类型,地址,但它总是给收件箱和发件箱提供相同的结果.我的示例代码是

Uri SMS_INBOX = Uri.parse("content://sms");
        c = getContentResolver().query(SMS_INBOX, null, "thread_id" + " = "
                        + "3", null,
                        "date" + " ASC");
        if(c.moveToFirst()){
            count.add(c.getCount());
            for(int j=0;j<c.getCount();j++){
                System.out.println(c.getString(c.getColumnIndexOrThrow("body")).toString());
                System.out.println("new   person=="+c.getColumnIndex("person")+"type=="+c.getColumnIndexOrThrow("type"));
                c.moveToNext();
            }
        }
        c.close();

请帮我.

我试图弄清楚如何将总数四舍五入到小数点后两位.总计是EditText.我不能把它缩小到只有两位小数.怎么了？谢谢你的帮助.

public void macro() {
    caloriesTotal = Double.parseDouble(calories.getText().toString());
    total = (caloriesTotal * .20)/9;
    DecimalFormat round = new DecimalFormat ("###.##");
    round.format(total);
    carbsTotal = (caloriesTotal * .40)/4;
    proteinTotal = (caloriesTotal * .40)/4;       
    fat.setText(Double.toString(total));
    carbs.setText(Double.toString(carbsTotal));
    protein.setText(Double.toString(proteinTotal));
}

我正在使用onTouchListener进行布局。我想在布局之外点击。我为布局设置了onTouchListetener。但是运动事件始终显示ACTION_DOWN。即使我触摸视图外，它也没有显示ACTION_OUTSIDE。谁能帮助我找出为什么它没有显示恒定的ACTION_OUTSIDE。这是我正在使用的代码

Layout.setOnTouchListener(new View.OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        Log.i("action",event.getAction()+"");
        if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {
            Toast.makeText(getApplicationContext(), "check", Toast.LENGTH_SHORT).show();
            return true;
        }

        return false;
    }
});

您好我想单击一个按钮,每次单击它时都会向表行添加一个新按钮.在向行添加了3个按钮后,我想动态创建一个新的表行并向其添加一个新按钮.

我知道如果单击一个按钮,如何将一个按钮添加到tableLayout.我不知道每次点击时如何修改表格行,所以我可以添加一个额外的按钮.

任何建议都会非常有帮助和赞赏.

以下是我的代码,但这并不完美

public class DynamicTableView extends Activity {

    TableLayout mTlayout;
    String[] mTextofButton = { "Dipak", "E", "I", "J", "L",
            "M", "G", "R", "N", "T", "H", "P",
            "K", "Y", "V" };

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mTlayout = (TableLayout) findViewById(R.id.mTlayout);


        TableRow tr=new TableRow(this);
        for(int i=0;i<mTextofButton.length;i++){
            Button btn=new Button(this);
            btn.setText(mTextofButton[i]);
            tr.addView(btn);

        }   
        mTlayout.addView(tr);
    }
}

提前致谢.

我有一个应用程序,用户按下按钮,弹出自定义微调器,以便用户可以选择九种颜色.当用户触摸背景时(除了旋转器之外的每个地方),我希望旋转器被解雇.这可能吗？

我试图在覆盖背景和调用的图像上添加onTouchListener

dialog.dismiss(); 

但它不起作用.

我的微调器是自定义Spinner,在xml文件中设置并弹出:

final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.colorchooser);

先感谢您

我有个问题,

当我在模拟器中测试它并在DDMS屏幕中编辑位置时,locationmanager工作得非常好,但是当我在三星Galaxy SII上测试它时,它的nog工作..

如何从下面的代码解决java.lang.StackOverflowError？

我的守则是: -

      private boolean mPickerMode=false;
