Android中DialogFragment自动弹出输入法

 只需要添加
 
      editTextPassword.setFocusable(true);
         editTextPassword.setFocusableInTouchMode(true);
         editTextPassword.requestFocus(); 和在onresume()方法里面定义键盘弹出的时间
 
     @Override
     public void onResume() {
         super.onResume();
         log.info("onResume");
         (new Handler()).postDelayed(new Runnable() {
             public void run() {
                 log.info("postDelayed");
                 InputMethodManager inManager = (InputMethodManager)editTextPassword.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
                 inManager.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);
             }
             },500);
     }
