我在我的应用程序中实现了PlacePicker.IntentBuilder UI.对于最长的它没有问题,但现在一旦UI出现,它关闭,我不知道为什么.疯狂的事情是看logcat它没有崩溃或导致任何异常,所以我不知道是什么问题.这是创建和调用它的类.

    package com.example.apthagreat.faf;
    import android.app.AlertDialog;
    import android.content.DialogInterface;
    import android.content.Intent;
    import android.os.AsyncTask;
    import android.support.v7.app.ActionBarActivity;
    import android.os.Bundle;
    import android.view.Menu;
    import android.view.MenuItem;
    import android.view.View;
    import android.widget.Button;
    import android.widget.EditText;
    import android.widget.Toast;

    import com.google.android.gms.location.places.Place;
    import com.google.android.gms.location.places.ui.PlacePicker;
    import com.google.android.gms.maps.model.LatLng;
    import com.google.android.gms.maps.model.LatLngBounds;

    public class DetermineSearchCoordinatesScreen extends ActionBarActivity
    {
        //Instance Variables
    int PLACE_PICKER_REQUEST = 1;
    int SELECTED_PLACE_REQUEST = 2; …

我试图设置移动数据.但它只是起作用SIM 1.

public static void setMobileData(Context context, boolean isEnabled) throws NoSuchFieldException, ClassNotFoundException, IllegalAccessException, NoSuchMethodException, InvocationTargetException {

    ConnectivityManager conman = (ConnectivityManager) context.getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
    @SuppressWarnings("rawtypes")
    final Class conmanClass = Class.forName(conman.getClass().getName());
    final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService");
    iConnectivityManagerField.setAccessible(true);
    final Object iConnectivityManager = iConnectivityManagerField.get(conman);
    final Class iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName());

    Class[] cArg = new Class[2];
    cArg[0] = String.class;
    cArg[1] = Boolean.TYPE;
    Method setMobileDataEnabledMethod;

    setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", cArg);

    Object[] pArg = new Object[2];
    pArg[0] = context.getPackageName();
    pArg[1] = isEnabled;
    setMobileDataEnabledMethod.setAccessible(true);
    setMobileDataEnabledMethod.invoke(iConnectivityManager, pArg);
}

public static void …

我有一个活动ListView。TextView在每个列表项中显示。使用这些方法切换选定位置的属性EditText#setTextIsSelectable，EditText#setEllipsize＆EditText#setSingleLine。单击第一个项目效果很好。但是当我点击另一个项目时，我得到了StackOverFlowError。

下面是我的代码示例。如果我有任何错误，请让我知道。

public class SelectableTextListActivity extends Activity {
    private static final String TAG = "HistoryActivity";

    private ListView listView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);//only ListView present in this layout
        listView = (ListView) findViewById(R.id.myList);
