我有一个EditText，它不允许聚焦和键入。屏幕具有CoordinatorLayout作为根/父级，以及带有ViewPager的NestedScrollView。
在顶部将有google map，在底部有两个标签。
第一个选项卡上的文本内容带有“编辑文本”（出现问题），第二个选项卡上有一个recyclerview。
在这种布局下，无法在“第一个”选项卡上的“焦点”和“编辑文本”上键入内容。

答案 0 :(得分：0)
您可以强制编辑文本以编程方式获得焦点。在TAB1 Java类中，您可以执行以下操作，以强制编辑文本获得焦点。
EditText editText = findViewById(R.id.test_text); //initialize edit text
editText.requestFocus(); //will request focus
//will force the keyboard to show
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
