Why EditText.getText shows null in Android?

Question

I have a very strange problem with EditText. I create a form in my app with Edit Texts and I get their content into string value but its empty and shows nothing.

XML code:

 <EditText
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:gravity="center"
        android:id="@+id/name"
        style="@style/Edittext_form1"
        android:inputType="text"
        android:hint="@string/name"/>

java code:

 private EditText _name;

 public  static  String name;

        _name = (EditText) findViewById(R.id.name);
        name = _name.getText().toString().trim();

Toast.makeText(getApplicationContext(),name,Toast.LENGTH_LONG).show();;

Answer 1

Your problem is about to get the content of that resource before you set it.

Add this line to your Edittext tag:

android:text="some default text"

Answer 2

Take one EditText, Button and TextView and try this:

---

Main Activity:

    btnName.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            tvName.setText(etName.getText().toString());
        }
    });
