Question

当我收到PHONE_STATE意图时，如何在下面创建一个呼叫信息对话框

Answer 1

首先添加此权限

<uses-permission android:name="android.permission.READ_CONTACTS" />

在您的活动中使用LoaderManager.LoaderCallbacks接口，如下所示：

abstract Loader        onCreateLoader(int id, Bundle args)

//Instantiate and return a new Loader for the given ID.

abstract void      onLoadFinished(Loader loader, D data)

//Called when a previously created loader has finished its load.

abstract void      onLoaderReset(Loader loader)

//Called when a previously created loader is being reset, and thus making its data unavailable.

onCreateLoader（）的实现：

@Override
public Loader onCreateLoader(int loaderID, Bundle args) {
Log.d(TAG, "onCreateLoader() >> loaderID : " + loaderID);

switch (loaderID) {
case URL_LOADER:
// Returns a new CursorLoader
return new CursorLoader(
this,   // Parent activity context
CallLog.Calls.CONTENT_URI,        // Table to query
null,     // Projection to return
null,            // No selection clause
null,            // No selection arguments
null             // Default sort order
);
default:
return null;
}
}

在onLoadFinished（）方法中调用您的详细信息：

Override
    public void onLoadFinished(Loader loader, Cursor managedCursor) {
        Log.d(TAG, "onLoadFinished()");

        StringBuilder sb = new StringBuilder();

        int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER);
        int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE);
        int date = managedCursor.getColumnIndex(CallLog.Calls.DATE);
        int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION);

        sb.append("<h4>Call Log Details <h4>");
        sb.append("\n");
        sb.append("\n");

        sb.append("<table>");

        while (managedCursor.moveToNext()) {
            String phNumber = managedCursor.getString(number);
            String callType = managedCursor.getString(type);
            String callDate = managedCursor.getString(date);
            Date callDayTime = new Date(Long.valueOf(callDate));
            String callDuration = managedCursor.getString(duration);
            String dir = null;

            int callTypeCode = Integer.parseInt(callType);
            switch (callTypeCode) {
                case CallLog.Calls.OUTGOING_TYPE:
                    dir = "Outgoing";
                    break;

                case CallLog.Calls.INCOMING_TYPE:
                    dir = "Incoming";
                    break;

                case CallLog.Calls.MISSED_TYPE:
                    dir = "Missed";
                    break;
            }

            sb.append("<tr>")
                    .append("<td>Phone Number: </td>")
                    .append("<td><strong>")
                    .append(phNumber)
                    .append("</strong></td>");
            sb.append("</tr>");
            sb.append("<br/>");
            sb.append("<tr>")
                    .append("<td>Call Type:</td>")
                    .append("<td><strong>")
                    .append(dir)
                    .append("</strong></td>");
            sb.append("</tr>");
            sb.append("<br/>");
            sb.append("<tr>")
                    .append("<td>Date & Time:</td>")
                    .append("<td><strong>")
                    .append(callDayTime)
                    .append("</strong></td>");
            sb.append("</tr>");
            sb.append("<br/>");
            sb.append("<tr>")
                    .append("<td>Call Duration (Seconds):</td>")
                    .append("<td><strong>")
                    .append(callDuration)
                    .append("</strong></td>");
            sb.append("</tr>");
            sb.append("<br/>");
            sb.append("<br/>");
        }
        sb.append("</table>");

        managedCursor.close();

        callLogsTextView.setText(Html.fromHtml(sb.toString()));
    }
