新的一周，新的开始迎接新的挑战。今天简单介绍一下Android输入框被软键盘遮住的两种常用方法。
法一：清单文件对要进行设置的Activity属性配置android:windowSoftInputMode="adjustPan|adjustResize"
但经过测试会发现有时候标题栏也会被挤上去，怎么解决这样的问题呢 ？如果用法一的话这样的问题貌似解决不了
法二：
还有一种方法可以解决这样的问题 这种也是我在网上找的做下记录下次再用的话也不用去网上找了 ，首先把标题栏抽取到基类里面进行初始化等一些列的操作 ，然后对当前的Activity在OnCreate方法setContentView下配置AndroidBug5497Workaround.assistActivity(this);即可
AndroidBug5497Workaround可以放在工具类中，它的代码如下
public class AndroidBug5497Workaround {
public static void assistActivity (Activity activity) {
new AndroidBug5497Workaround(activity);
}
private ViewmChildOfContent;
private int usableHeightPrevious;
private FrameLayout.LayoutParamsframeLayoutParams;
private AndroidBug5497Workaround(Activity activity) {
FrameLayout content = (FrameLayout) activity.findViewById(android.R.id.content);
mChildOfContent = content.getChildAt(0);
mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
public void onGlobalLayout() {
possiblyResizeChildOfContent();
}
});
frameLayoutParams = (FrameLayout.LayoutParams)mChildOfContent.getLayoutParams();
}
private void possiblyResizeChildOfContent() {
int usableHeightNow = computeUsableHeight();
if (usableHeightNow !=usableHeightPrevious) {
int usableHeightSansKeyboard =mChildOfContent.getRootView().getHeight();
int heightDifference = usableHeightSansKeyboard - usableHeightNow;
if (heightDifference > (usableHeightSansKeyboard/4)) {
// keyboard probably just became visible
frameLayoutParams.height = usableHeightSansKeyboard - heightDifference;
}else {
// keyboard probably just became hidden
frameLayoutParams.height = usableHeightSansKeyboard;
}
mChildOfContent.requestLayout();
usableHeightPrevious = usableHeightNow;
}
}
private int computeUsableHeight() {
Rect r =new Rect();
mChildOfContent.getWindowVisibleDisplayFrame(r);
return (r.bottom - r.top);// 全屏模式下：return r.bottom
}
}
这种方法就可以解决标题栏不会被挤上去的情况了
