札记

笔记！
android:windowSoftInputMode="stateVisible|adjustResize"
                android:theme="@android:style/Theme.NoTitleBar"
                android:configChanges="orientation|keyboardHidden"
                android:theme="@style/Theme.CustomDialog"
                 android:theme="@style/Theme.Translucent"
                 android:theme="@style/Theme.Transparent"
       
        android:layout_width="0dip"
        android:layout_height="fill_parent"
        android:layout_weight="1"
       
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.SAMPLE_CODE" />
            </intent-filter>
           
            Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
            intent.setType("audio/*");
            startActivity(Intent.createChooser(intent, "Select music"));
           
        NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
              
友情提供了另一种方法：(得自峰的真传)
new NullPointerException("No focus window, dropping: ").printStackTrace();
  java.util.Map<Thread, StackTraceElement[]> ts = Thread.getAllStackTraces();
StackTraceElement[] ste = ts.get(Thread.currentThread());
for (StackTraceElement s : ste) {
android.util.Log.d("SS     ", s.toString());
}

Throwable tr = new Throwable();
tr.fillInStackTrace();
Log.v(TAG,"",tr);


打印JAVA调用栈方法


      try {
           throw new Exception();
       } catch (Exception ex) {
           Log.e("pan", "=======sssss======");
           ex.printStackTrace();
       }

有时候需要了解一段代码调用时的调用栈，方便定位问题，使用上面的方法可以打印调用栈，很方便。

打印结果如下:从下向上是调用逻辑。
