Android 软键盘弹出自动移动布局

2行代码搞定软键盘布局上移

当我们在使用登录界面的时候，软键盘弹出经常会挡住输入框或者登录按钮

一般应用都没有处理，处理的也是很粗糙，所以我写了一个自定义控件解决该问题。

想移动谁就移动谁，so easy ！！！！！

public class KeyboardMoveLayout extends LinearLayout {
private OnSizeChangedListener mChangedListener;
private boolean isShowKeyboard = false;

public KeyboardMoveLayout(Context context) {
super(context);
}

public KeyboardMoveLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}

public KeyboardMoveLayout(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}

@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
if (null != mChangedListener && 0 != oldw && 0 != oldh) {
if (h < oldh) {
isShowKeyboard = true;
} else {
isShowKeyboard = false;
}
mChangedListener.onChanged(isShowKeyboard);
}
}

public void setOnSizeChangedListener(OnSizeChangedListener listener) {
mChangedListener = listener;
}

public interface OnSizeChangedListener {
void onChanged(boolean showKeyboard);
}
}

上面的KeyboardMoveLayout自定义控件主要用于监听软键盘的弹出或者关闭，该自定义控件一般放在一级根布局或者二级根布局。

想移动谁，就把ScrollView包裹在谁身上

上面是demo的xml布局。

}

最后需要在Activity中增加<span style="font-size:32px;color:#ff0000;">android:windowSoftInputMode="adjustResize|stateHidden"</span>
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="test.inke.com.test">

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:windowSoftInputMode="adjustResize|stateHidden">
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

</manifest>
