试试这个:

android:inputType="none"

我用一个对话框来解决这个问题。

    AlertDialog dialog;
    EditText _editID;
    TextView _txtID;

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_principal);
        _txtID = (TextView) findViewById(R.id._txtID);
        dialog = new AlertDialog.Builder(this).create();
        _editID = new EditText(this);
        _editID.setInputType(InputType.TYPE_NUMBER_FLAG_SIGNED);
        dialog.setTitle("Numero do Registro:");
        dialog.setView(_editID);
        dialog.setButton(DialogInterface.BUTTON_POSITIVE, "IR", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                _txtID.setText(_editID.getText());
                toId(Integer.parseInt((_editID.getText().toString())));
            }
        });
        dialog.setButton(DialogInterface.BUTTON_NEGATIVE, "CANCELAR", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });

        _txtID.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                _txtID.setText("_editID.getText()");
                //_editID.setText("");
                dialog.show();

            }
        });

如果你想在java代码中这样做，只需使用这一行来禁用它:

editText.setEnabled(false);

这是为了启用它:

editText.setEnabled(true);

<EditText
    android:id="@+id/txtDate"
    android:layout_width="140dp"
    android:layout_height="wrap_content"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="10dp"
    android:layout_marginTop="2dp"
    android:clickable="false"
    android:cursorVisible="false"
    android:gravity="center" />

并使用以下:

txtDate.setKeyListener(null);

试试这个:

android:inputType="none"

Try

.setInputType(InputType.TYPE_NULL);
