在我的主要活动中有一个按钮.在它的onclick监听器我调用功能来设置闹钟.警报正在工作,但我无法阻止它.可以帮助我一些人

MainActivity.java

public class MainActivity extends Activity {

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

        findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                setalarm();
            }


        });
    }

    private void setalarm() {

        Calendar cal=Calendar.getInstance();
        // cal.set(Calendar.MONTH,6);
        // cal.set(Calendar.YEAR,2013);
        // cal.set(Calendar.DAY_OF_MONTH,12);
        cal.set(Calendar.HOUR_OF_DAY,18);
        cal.set(Calendar.MINUTE,32);
        Intent intent = new Intent(this, Mote.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 1253, intent, PendingIntent.FLAG_UPDATE_CURRENT|  Intent.FILL_IN_DATA);

        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

        alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),pendingIntent );
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
        Toast.makeText(this, "Alarm SET.", Toast.LENGTH_LONG).show();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) { …

在sdk更新后我无法创建一个hello world应用程序.我的build.gradle看起来像这样

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.coders.yo"
        minSdkVersion 11
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
}

但是构建失败并显示出来

Error:A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugCompile'.
   > Could not find com.android.support:support-v4:22.0.0.
     Required by:
         Yo:app:unspecified > com.android.support:appcompat-v7:22.0.0

所以我添加了编译'com.android.support:support-v4:22.0.0.' 现在我明白了

Error:Failed to find: com.android.support:support-v4:22.0.0.

我一直在研究短信应用程序.直到昨天,当我将Nexus 4更新为Android 4.4,KitKat时,一切顺利.诸如将SMS标记为已读/未读以及删除线程中的所有消息等功能已停止工作.为什么会这样？它适用于其他三星设备(不运行KitKat).

这是我将邮件标记为已读或未读的代码:

public static void markRead(final Context context, final Uri uri,
            final int read) {
        Log.d(TAG, "markRead(" + uri + "," + read + ")");
        if (uri == null) {
            return;
        }
        String[] sel = Message.SELECTION_UNREAD;
        if (read == 0) {
            sel = Message.SELECTION_READ;
        }
        final ContentResolver cr = context.getContentResolver();
        final ContentValues cv = new ContentValues();
        cv.put(Message.PROJECTION[Message.INDEX_READ], read);
        try {
            cr.update(uri, cv, Message.SELECTION_READ_UNREAD, sel);
        } catch (IllegalArgumentException e) {
            Log.e(TAG, "failed update", e);
            Toast.makeText(context, e.getMessage(), Toast.LENGTH_LONG).show();
        }
} …

我试图使用android httpclient(loopj)发布一些数据.我在其正文中添加一些json数据并设置请求标头.但它显示AsyncHttpClient:将忽略Passed contentType,因为HttpEntity设置了内容类型.有谁知道如何解决这个问题？

 public static void post(Activity context,String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
        try {
            JSONObject jsonParams = new JSONObject();
            JSONObject innerObject = new JSONObject();
            innerObject.put("Name", "@MODE");
            innerObject.put("ParamType", "8");
            innerObject.put("Value", "0");
            JSONArray ar = new JSONArray();
            ar.put(innerObject);
            try {
                jsonParams.put("ProcName", "Core.MENUS_SPR");
                jsonParams.put("dbparams", ar);

               Log.i("jsonParams.toString()",""+jsonParams.toString());

                StringEntity se = null;
                try {
                    se = new StringEntity(jsonParams.toString());


                } catch (UnsupportedEncodingException e) {
                    e.printStackTrace();
                    return;
                }
                   client.post(context, (url), se, "application/json", responseHandler);


            } catch (JSONException e) {
                e.printStackTrace();
            }

      } catch (Exception e) { …
