EditText失去焦点隐藏软键盘

1, 页面根布局加

android :focusable= "true"

android :focusableInTouchMode= "true"

2.在activity里面重写  dispatchTouchEvent

@Override

public boolean dispatchTouchEvent(MotionEvent ev) {

if (ev.getAction() == MotionEvent. ACTION_DOWN ) {

View v = getCurrentFocus();

if (ViewUtil. isShouldHideInput ( v, ev )) {

InputMethodManager imm = (InputMethodManager) getSystemService( Context. INPUT_METHOD_SERVICE );

if (imm != null ) {

imm.hideSoftInputFromWindow(v.getWindowToken(), 0 );

}

}

return super .dispatchTouchEvent( ev );

}

// 必不可少，否则所有的组件都不会有TouchEvent了

if (getWindow().superDispatchTouchEvent( ev )) {

return true ;

}

return onTouchEvent( ev );

}

/**

* 是否隐藏键盘

* @param v

* @param event

* @return

*/

public static boolean isShouldHideInput(View v, MotionEvent event) {

if (v != null && (v instanceof EditText)) {

int [] leftTop = { 0 , 0 };

//获取输入框当前的location位置

v.getLocationInWindow( leftTop );

int left = leftTop[ 0 ];

int top = leftTop[ 1 ];

int bottom = top + v.getHeight();

int right = left + v.getWidth();

if (event.getX() > left && event.getX() < right

&& event.getY() > top && event.getY() < bottom) {

// 点击的是输入框区域，保留点击EditText的事件

return false ;

} else {

return true ;

}

}

return false ;

}
