android dialog 可以获取到button点击事件，但是获取不到输入的值

public void alertAddClass(){AlertDialog.Builder builder = new AlertDialog.Builder(mContext);final AlertDialog dialog = builder.create();final View dialogView = View.inflate(mContext, R.layout.dialog_add_class, null);//设置对话框布局dialog.setView(dialogView);// 点击对话框外面不会消失，返回键起作用dialog.setCanceledOnTouchOutside(false);dialog.setTitle("课程添加");dialog.show();Button btnAddClass = dialogView.findViewById(R.id.bt_addClass);Button btnCancelAdd = dialogView.findViewById(R.id.bt_cancelAdd);final EditText etDay = dialogView.findViewById(R.id.et_Day);final EditText etName = dialogView.findViewById(R.id.et_Name);final EditText etTime = dialogView.findViewById(R.id.et_Time);final EditText etAddress = dialogView.findViewById(R.id.et_Address);// 添加课程btnAddClass.setOnClickListener(new View.OnClickListener() {String classDay = etDay.getText().toString().trim(); // 这里获取不到值***String className = etName.getText().toString().trim();

Answer 1

btnAddClass.setOnClickListener(new View.OnClickListener() {
//你的数据获取是在哪个位置？
//String classDay = etDay.getText().toString().trim();
//String className = etName.getText().toString().trim();
 public void onClick(View view) {
       String classDay = etDay.getText().toString().trim();
       String className = etName.getText().toString().trim();
   }

把dialog.show(),放在点击事件的后面试试

Answer 3

少年啊，你的edittext要申请焦点吧

Answer 4

btnAddClass.setOnClickListener(new View.OnClickListener() {

//你的数据获取是在哪个位置？

//String classDay = etDay.getText().toString().trim();

//String className = etName.getText().toString().trim();

public void onClick(View view) {

String classDay = etDay.getText().toString().trim();

String className = etName.getText().toString().trim();

}btnAddClass.setOnClickListener(new View.OnClickListener() {

//你的数据获取是在哪个位置？

//String classDay = etDay.getText().toString().trim();

//String className = etName.getText().toString().trim();

public void onClick(View view) {

String classDay = etDay.getText().toString().trim();

String className = etName.getText().toString().trim();

}
