Android:windowSoftInputMode=＂adjustResize＂无效解决方法

时间：2018-08-16     来源：未知

Android开发中用到软键盘时会出现设置Activity的windowSoftInputMode="adjustResize"失效的问题，这时我们可以在activity的根布局上添加fitsSystemWindows="true"，然后adjustResize属性就会起作用。但是这样做还有一个问题，我们的Actionbar会下移一段距离，这段距离的高度相当于状态栏的高度。那么我们该如何解决这个问题，完美使用android adjustresize属性呢?

解决这个问题我们需要自定义一个layout做我们的根布局，在layout中重写fitSystemWindows()和onApplyWindowInsets()方法，具体如下：

public class MyLinearLayout extends LinearLayout{

private int[] mInsets = new int[4];

public MyLinearLayout(Context context) {

super(context);

}

public MyLinearLayout(Context context, AttributeSet attrs) {

super(context, attrs);

}

public MyLinearLayout(Context context, AttributeSet attrs, int defStyleAttr) {

super(context, attrs, defStyleAttr);

}

@TargetApi(Build.VERSION_CODES.LOLLIPOP)

public MyLinearLayout(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {

super(context, attrs, defStyleAttr, defStyleRes);

}

@Override

protected final boolean fitSystemWindows(Rect insets) {

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

// Intentionally do not modify the bottom inset. For some reason,

// if the bottom inset is modified, window resizing stops working.

// TODO: Figure out why.

mInsets[0] = insets.left;

mInsets[1] = insets.top;

mInsets[2] = insets.right;

insets.left = 0;

insets.top = 0;

insets.right = 0;

}

return super.fitSystemWindows(insets);

}

@Override

public final WindowInsets onApplyWindowInsets(WindowInsets insets) {

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {

mInsets[0] = insets.getSystemWindowInsetLeft();

Log.e("mInsets[0]",""+mInsets[0]);

mInsets[1] = insets.getSystemWindowInsetTop();

Log.e("mInsets[1]",""+mInsets[1]);

mInsets[2] = insets.getSystemWindowInsetRight();

Log.e("mInsets[2]",""+mInsets[2]);

return super.onApplyWindowInsets(insets.replaceSystemWindowInsets(0, 0, 0,

insets.getSystemWindowInsetBottom()));

} else {

return insets;

}}}

经过以上的操作之后，就可以很完美的解决windowSoftInputMode="adjustResize"无效问题了，分享就到这里，如果对大家有所帮助，请继续关注我们，我们会持续更新更多优质技术文章!
