Android Can'；t在弹出式活动中编辑编辑文本

我使用的是弹出式活动（这是一种通过android:theme=“@android:style/theme.Dialog”扩展活动的活动）。它包含编辑文本，但不可编辑

所有类似的问题都是关于弹出窗口而不是弹出活动的，它们在这里不起作用

这是活动：

public class BugActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_bug);
        EditText title = (EditText) findViewById(R.id.bug_subject);
        title.setFocusable(true);
        title.setText("");
        EditText content = (EditText) findViewById(R.id.bug_content);
        DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        int wi = dm.widthPixels;
        int hi = dm.heightPixels;
        getWindow().setLayout((int) (wi * .84), (int) (hi * .8));
    }

    @Override
    public void onAttachedToWindow() {
        super.onAttachedToWindow();

        View view = getWindow().getDecorView();
        WindowManager.LayoutParams lp = (WindowManager.LayoutParams) view.getLayoutParams();
        lp.gravity = Gravity.CENTER | Gravity.TOP;
        lp.y = 10;

        getWindowManager().updateViewLayout(view, lp);
    }
}

    <TextView

        android:layout_height="wrap_content"

        android:text="@string/message"
        android:layout_marginLeft="10dp"
        android:layout_marginStart="10dp"

        android:layout_marginTop="10dp"
        android:textSize="17dp">

    </EditText>

这是布局：

public class BugActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_bug);
        EditText title = (EditText) findViewById(R.id.bug_subject);
        title.setFocusable(true);
        title.setText("");
        EditText content = (EditText) findViewById(R.id.bug_content);
        DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        int wi = dm.widthPixels;
        int hi = dm.heightPixels;
        getWindow().setLayout((int) (wi * .84), (int) (hi * .8));
    }

    @Override
    public void onAttachedToWindow() {
        super.onAttachedToWindow();

        View view = getWindow().getDecorView();
        WindowManager.LayoutParams lp = (WindowManager.LayoutParams) view.getLayoutParams();
        lp.gravity = Gravity.CENTER | Gravity.TOP;
        lp.y = 10;

        getWindowManager().updateViewLayout(view, lp);
    }
}

我尝试使用requestFocus和setFocusable（）但仍然不起作用
