Android 解决输入法键盘遮盖布局问题，程序员不得不用的方案，快捷！

/**
* @param root 最外层布局，需要调整的布局
* @param scrollToView 被键盘遮挡的scrollToView，滚动root,使scrollToView在root可视区域的底部
*/

private void listenKeyboardLayout(final LinearLayout root, final View scrollToView) {
SoftKeyboardStateHelper keyboardStateHelper = new SoftKeyboardStateHelper(root);
keyboardStateHelper.addSoftKeyboardStateListener(new SoftKeyboardStateListener() {

@Override
public void onSoftKeyboardOpened(int keyboardHeightInPx) {
Rect rect = new Rect();
// 获取root在窗体的可视区域
root.getWindowVisibleDisplayFrame(rect);
int[] location = new int[2];
// 获取scrollToView在窗体的坐标
scrollToView.getLocationInWindow(location);
// 计算root滚动高度，使scrollToView在可见区域的底部
int srollHeight = (location[1] + scrollToView.getHeight()) - rect.bottom;
root.scrollTo(0, srollHeight);
}

@Override
public void onSoftKeyboardClosed() {
// 键盘隐藏
root.scrollTo(0, 0);
}
});
}

在此要获取SoftKeyboardStateHelper类

效果图如下：





下面提供完整的代码及布局文件：

MainActivity

public class MainActivity extends Activity {

private LinearLayout mRoot;
private Button mSubmit;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mRoot = (LinearLayout) findViewById(R.id.root);
mSubmit = (Button) findViewById(R.id.submit);
listenKeyboardLayout(root, mSubmit);
}

/**
* @param root 最外层布局，需要调整的布局
* @param scrollToView 被键盘遮挡的scrollToView，滚动root,使scrollToView在root可视区域的底
*/

private void listenKeyboardLayout(final LinearLayout root, final View scrollToView) {

SoftKeyboardStateHelper keyboardStateHelper = new SoftKeyboardStateHelper(root);

keyboardStateHelper.addSoftKeyboardStateListener(new SoftKeyboardStateListener() {

@Override
public void onSoftKeyboardOpened(int keyboardHeightInPx) {
Rect rect = new Rect();
// 获取root在窗体的可视区域
root.getWindowVisibleDisplayFrame(rect);
int[] location = new int[2];
// 获取scrollToView在窗体的坐标
scrollToView.getLocationInWindow(location);
// 计算root滚动高度，使scrollToView在可见区域的底部
int srollHeight = (location[1] + scrollToView.getHeight()) - rect.bottom;
root.scrollTo(0, srollHeight);
}

@Override
public void onSoftKeyboardClosed() {
// 键盘隐藏
root.scrollTo(0, 0);
}
});
}
