Android平台4.2.2与Cordova2.2.0结合使用后出现软键盘弹出后，覆盖输入域问题，在Android的4.0.3中测试没有这样的问题，设置AndroidManifest.xml中的activity的android:windowSoftInputMode="adjustPan"不起作用，通过google发现者可能是android的一个bug或者是cordova的bug。。。
借鉴了网上的一种写法
代码如下：
package com.siro.androidwebviewos.utils;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.graphics.Rect;
import android.util.Log;
import android.view.View;
import android.view.ViewTreeObserver;
import android.widget.FrameLayout;
import com.siro.androidwebviewos.action.OpenNewActivity;
@SuppressLint("NewApi")
public class AndroidBug5497Workaround {
public static void assistActivity (OpenNewActivity activity) {
new AndroidBug5497Workaround(activity);
}
private View rootView ;
private int mLastHeightDifferece ;
private AndroidBug5497Workaround(Activity activity) {
rootView = activity.findViewById(android.R.id.content);
rootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
public void onGlobalLayout() {
checkHeightDifference();
}
});
}
private void checkHeightDifference(){
// get screen frame rectangle
Rect r = new Rect();
rootView.getWindowVisibleDisplayFrame(r);
int screenHeight = rootView.getRootView().getHeight();
int heightDifference = screenHeight - (r.bottom - r.top);
if (heightDifference > screenHeight/3 && heightDifference != mLastHeightDifferece) {
rootView.getLayoutParams().height = screenHeight - heightDifference;
rootView.requestLayout();
mLastHeightDifferece = heightDifference;
} else if (heightDifference != mLastHeightDifferece) {
rootView.getLayoutParams().height = screenHeight;
rootView.requestLayout();
mLastHeightDifferece = heightDifference;
}
}
}
activity中调用：
在loadUrl后调用
AndroidBug5497Workaround.assistActivity(this);
效果不理想，虽然有屏幕上推的效果，但是，输入域还是被覆盖。
经过同事提醒改变了一下写法，效果还可以。
public class OpenNewActivity extends DroidGap implements OnTouchListener 实现OnTouchListener
重写onTouch方法，主要获取getRawY
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
eventX = event.getRawX() ;
eventY = event.getRawY() ;
}
return false;
}
oncreate方法的loadUrl之后增加对rootView的监听：
rootView = this.findViewById(android.R.id.content);
rootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
public void onGlobalLayout() {
checkHeightDifference();
}
});
通过当前屏幕高度，弹出后的软键盘高度及所点击输入域的RawY。计算rootView的位移量，并且requestLayout();
@SuppressLint("NewApi")
private void checkHeightDifference(){
Rect r = new Rect();
rootView.getWindowVisibleDisplayFrame(r);
int screenHeight = rootView.getRootView().getHeight();
int heightDifference = screenHeight - (r.bottom - r.top);
if (heightDifference > screenHeight/3 && heightDifference != mLastHeightDifferece) {
rootView.setTranslationY(- (heightDifference - ( screenHeight - eventY)+20));
rootView.requestLayout();
mLastHeightDifferece = heightDifference;
} else if (heightDifference != mLastHeightDifferece) {
rootView.setTranslationY(heightDifference);
rootView.requestLayout();
mLastHeightDifferece = heightDifference;
}
}
onTouch
