Android 点击空白处自动隐藏输入法

方法1: 简单但有时会无效
InputMethodManager manager= (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
@Override
public boolean onTouchEvent(MotionEvent event) {
// TODO Auto-generated method stub
if(event.getAction() == MotionEvent.ACTION_DOWN){
if(getCurrentFocus()!=null && getCurrentFocus().getWindowToken()!=null){
manager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
}
}
return super.onTouchEvent(event);
}

方法2: 完美适用activity与fragment

// -------------------------------------隐藏输入法-----------------------------------------------------
// 获取点击事件
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
// TODO Auto-generated method stub
if (ev.getAction() == MotionEvent.ACTION_DOWN) {
View view = getCurrentFocus();
if (isHideInput(view, ev)) {
HideSoftInput(view.getWindowToken());
}
}
return super.dispatchTouchEvent(ev);
}
// 判定是否需要隐藏
private boolean isHideInput(View v, MotionEvent ev) {
if (v != null && (v instanceof EditText)) {
int[] l = { 0, 0 };
v.getLocationInWindow(l);
int left = l[0], top = l[1], bottom = top + v.getHeight(), right = left
+ v.getWidth();
if (ev.getX() > left && ev.getX() < right && ev.getY() > top
&& ev.getY() < bottom) {
return false;
} else {
return true;
}
}
return false;
}
// 隐藏软键盘
private void HideSoftInput(IBinder token) {
if (token != null) {
InputMethodManager manager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
manager.hideSoftInputFromWindow(token,
InputMethodManager.HIDE_NOT_ALWAYS);
}
}
