根据前人经验总结
- 普通Activity(不带WebView),直接使用
adjustpan
或者adjustResize
- 如果带WebView:
- a) 如果非
全屏模式
,可以使用adjustResize
- b) 如果是
全屏模式
,则使用AndroidBug5497Workaround
进行处理。
- a) 如果非
常见方法
<activity
android:name=".MainActivity"
android:windowSoftInputMode="adjustPan" >
...
</activity>
最终方法
- 把
AndroidBug5497Workaround
类复制到项目中 - 在需要填坑的activity的onCreate方法中添加一句
AndroidBug5497Workaround.assistActivity(this)
即可。
AndroidBug5497Workaround类
public class AndroidBug5497Workaround {
// For more information, see https://code.google.com/p/android/issues/detail?id=5497
// To use this class, simply invoke assistActivity() on an Activity that already has its content view set.
public static void assistActivity (Activity activity) {
new AndroidBug5497Workaround(activity);
}
private View mChildOfContent;
private int usableHeightPrevious;

mChildOfContent.getWindowVisibleDisplayFrame(r);
return (r.bottom - r.top);// 全屏模式下: return r.bottom
}
}
