我有两个编辑文本，即手机和密码，当活动可见时，移动编辑文本可聚焦，同时完成输入手机号码我想检查验证并按下键盘返回键盘关闭并希望专注于密码编辑文本并使用密码执行相同的过程。我可以这样做。 代码： -
private void init() {
m_MainLayout = (LinearLayout) findViewById(R.id.mainLayout);
/*check whether SoftKeyPad open or hide*/
m_MainLayout.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
int heightDiff = m_MainLayout.getRootView().getHeight() - m_MainLayout.getHeight();
if (heightDiff > 100) { // if more than 100 pixels, its probably a keyboard...
} else {/*if hide then clear focus from Password Edit text*/
m_InputPassword.clearFocus();
checkFieldsForEmpty();
}
}
});
m_LoginBtn = (AppCompatButton) findViewById(R.id.btn_Login);// finding Id login botton
m_InputMobile = (EditText) findViewById(R.id.input_mobile);// finding Id of Mobile Number edit text
/*set focus change listener on Mobile Number Edit text*/
m_InputMobile.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
/*if mobile Edit text looses focus then....*/
if (!hasFocus) {
isValidMobile();// initalize method
}
}
});
/* set Editor action listener on Mobile number Edit text*/
m_InputMobile.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
/*if after input enter next keyWord*/
if (actionId == EditorInfo.IME_ACTION_NEXT) {
m_InputPassword.requestFocus();// then Request Password Edi text field to focus
}
return false;
}
});
m_InputPassword = (EditText) findViewById(R.id.input_password);// finding Id of assword editText
m_InputPassword.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);// defining password edit Tect Input type
m_InputPassword.setTransformationMethod(PasswordTransformationMethod.getInstance());
/*set Foucs change listener on password Edit text*/
m_InputPassword.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
/*if password field loose focus*/
if (!hasFocus) {
isValidPassword();
}
}
});
/*Adding Editor action listener*/
m_InputPassword.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE || actionId == EditorInfo.IME_ACTION_NEXT) {

checkFieldsForEmpty();
}
return false;
}
});
}
/*validation for mobile number*/

}
}

}
}
/*This method check Edit text is empty or not*/
