安卓：越来越软键盘高度 [英] Android : getting soft keyboard height

问题描述

正如标题，我只是想获得键盘高度。

As the title, I just want to get the keyboard height.

由于有在Android手机上这么多的分辨率，这是很难处理的。

Since there are so many resolution on Android phones, it is hard to handle.

那么，有没有API是什么？

So Is there any API for that?

感谢所有。

推荐答案

在您的活动中使用此code：

Use this code in your Activity:

 iSoftkeyboardHeight = viewMain.getHeight(); // viewMain - root view of your activity

 int y = iSoftkeyboardHeight - 2;
 int x = 10;
 int counter = 0;
 int height = y;
 int iSoftkeyboardHeightNow = 0;
 Instrumentation instrumentation = new Instrumentation();
 while( true)
  {
    final MotionEvent m = MotionEvent.obtain(  SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, x, y, 0);
    final MotionEvent m1 = MotionEvent.obtain( SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP,   x, y, 0);
    boolean ePointerOnSoftkeyboard = false;

    try
      {
        instrumentation.sendPointerSync(m);
        instrumentation.sendPointerSync(m1);
      }
     catch (SecurityException e)
      {
         ePointerOnSoftkeyboard = true;
      }
    if( !ePointerOnSoftkeyboard)
      {
        if( y == height)
          {
            if( counter++ < 100)
              {
                Thread.yield();
                continue;
              }
          }
         else
          if( y > 0)
            iSoftkeyboardHeightNow = iSoftkeyboardHeight - y;
        break;
      }
    y--;
    m.recycle();
    m1.recycle();
  }
 if( iSoftkeyboardHeightNow > 0)  iSoftkeyboardHeight = iSoftkeyboardHeightNow;
  else iSoftkeyboardHeight = 0;

 // now use iSoftkeyboardHeight
