Android webView 软键盘覆盖输入框，webView页面底部显示不全

1.软键盘覆盖输入框

【解决】

1.1AndroidManifest.xml

<activity
android:name=".activity.FindDetailsActivity"
android:windowSoftInputMode="stateHidden|adjustPan" />

1.2 添加类（该类是独立类）
/**

*/
public class AndroidBug5497Workaround {

private static final String TAG = "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 Activity activity;
private FrameLayout.LayoutParams frameLayoutParams;
private View mChildOfContent;
private int usableHeightPrevious;

private int statusBarHeight;//状态栏高度

private AndroidBug5497Workaround(Activity activity) {
this.activity = activity;
FrameLayout content = (FrameLayout) activity.findViewById(android.R.id.content);
mChildOfContent = content.getChildAt(0);
mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
public void onGlobalLayout() {//全局视图
possiblyResizeChildOfContent();
}
});
frameLayoutParams = (FrameLayout.LayoutParams) mChildOfContent.getLayoutParams();
}

/**可能调整内容的子内容*/
private void possiblyResizeChildOfContent() {
//获得有效高度
int usableHeightNow = computeUsableHeight();
LogUtils.v(TAG,"有效高度："+usableHeightNow);
if (usableHeightNow != usableHeightPrevious) {
int usableHeightSansKeyboard = mChildOfContent.getRootView().getHeight();
LogUtils.v(TAG,"全屏高度："+usableHeightSansKeyboard);

//这个判断是为了解决19之前的版本不支持沉浸式状态栏导致布局显示不完全的问题(使用沉浸式状态栏时使用改判断)
// if(Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT){
// Rect frame = new Rect();
// activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);
// int statusBarHeight = frame.top;
// usableHeightSansKeyboard -= statusBarHeight;
// }

int heightDifference = usableHeightSansKeyboard - usableHeightNow;
LogUtils.v(TAG, "默认高度：" + heightDifference);
if (heightDifference > (usableHeightSansKeyboard/4)) {
// keyboard probably just became visible（键盘可能是可见的）
frameLayoutParams.height = usableHeightNow;
} else {
// keyboard probably just became hidden（键盘可能是隐藏的）
frameLayoutParams.height = usableHeightSansKeyboard-statusBarHeight;
}
mChildOfContent.requestLayout();//重新设置自己位置
usableHeightPrevious = usableHeightNow;
}
}

/**计算有效高度*/
private int computeUsableHeight() {

Rect r = new Rect();
mChildOfContent.getWindowVisibleDisplayFrame(r);
statusBarHeight = r.top;

LogUtils.v(TAG,"状态栏高度："+statusBarHeight);
LogUtils.v(TAG,"我的布局高度（包含状态栏）："+r.bottom);//从顶到加载布局控件底部距离

/* 这个判断是为了解决19之后的版本在弹出软键盘时，
键盘和推上去的布局（adjustResize）之间有黑色区域的问题
使用沉浸式状态栏时使用改判断（未检验用时调节）*/
// if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
// return (r.bottom - r.top)+statusBarHeight;
// }

return (r.bottom - r.top);
}

}1.3 调用上面类-加载布局页面-加载布局方法
@Override
public void setRootView() {
super.setRootView();
setContentView(R.layout.activity_find_details);
AndroidBug5497Workaround.assistActivity(this);//防止软件盘遮挡网页输入框内容
context = this;
}1.4完成
【说明】

通过改变AndroidBug5497Workaround 类解决 侵入式状态栏 中显示网页不全问题
