 先设置监听事件
 private void edit_pass() {
         tw = new TextWatcher() {
             // @Override
             public void beforeTextChanged(CharSequence s, int start, int count,
                     int after) {

             }

             // @Override
             public void onTextChanged(CharSequence s, int start, int before,
                     int count) {
                 Log.w("Log", "----" + s);

             }

             // @Override
             public void afterTextChanged(Editable s) {
                 if (s.toString().length() == 1) {
                     if (pass1.isFocused()) {
                         pass1.clearFocus();
                         pass2.requestFocus();
                     } else if (pass2.isFocused()) {
                         pass2.clearFocus();
                         pass3.requestFocus();
                     } else if (pass3.isFocused()) {
                         pass3.clearFocus();
                         pass4.requestFocus();
                     } else if (pass4.isFocused()) {
                         pass4.clearFocus();
                         InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                         imm.hideSoftInputFromWindow(pass4.getWindowToken(), 0);
                     }
                 }
             }

         };
     }
 2.监听edittext
 pass1 = (EditText) findViewById(R.id.edit_pass1);
  pass2 = (EditText) findViewById(R.id.edit_pass2);
  pass3 = (EditText) findViewById(R.id.edit_pass3);
  pass4 = (EditText) findViewById(R.id.edit_pass4);
  pass1.addTextChangedListener(tw);
  pass2.addTextChangedListener(tw);
  pass3.addTextChangedListener(tw);
  pass4.addTextChangedListener(tw);
 这就可以，每当你输完一个输入框的时候，焦点自动切到第二个输入框，看效果图
