Android键盘操作

#### （1）打开键盘

```java
/**
 * 打开软键盘
 */
public static void openSoftKeyInput(Activity activity, EditText editText){
    InputMethodManager imm = (InputMethodManager)activity.getSystemService(INPUT_METHOD_SERVICE);
    //boolean isOpen=imm.isActive();//isOpen若返回true，则表示输入法打开
    if (!imm.isActive()){
        editText.requestFocus();
        //第二个参数可设置为0
        //imm.showSoftInput(et_content, InputMethodManager.SHOW_FORCED);//强制显示
        imm.showSoftInputFromInputMethod(activity.getCurrentFocus().getWindowToken(),
                InputMethodManager.SHOW_FORCED);
    }
}
/**
 * 强制打开软键盘
 */
public static void openSoftKeyInputForce(Activity activity, EditText editText) {
    InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
    inputMethodManager.showSoftInput(editText, 0);
}
```
（2）关闭

```java
if(getCurrentFocus()!=null){
     ((InputMethodManager)getSystemService(INPUT_METHOD_SERVICE))
        .hideSoftInputFromWindow(getCurrentFocus()
        .getWindowToken(),
        InputMethodManager.HIDE_NOT_ALWAYS);
}

```
