    sr_txt = findViewById(R.id.sr_txt);
    listView = findViewById(R.id.listView);
    databaseReference = FirebaseDatabase.getInstance().getReference("dreamapp");
    dream1 = new Dream();

嗨,我找到了解决方案,当我添加了一个arrayadapter和listview,然后我在searchview中使用它,然后它工作了,如果我搜索其中的确切单词,它就会得到结果,

 sr_txt.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            MainActivity.this.arrayAdapter.getFilter().filter(query);
            MainActivity.this.arrayAdapter2.getFilter().filter(query);
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            MainActivity.this.arrayAdapter.getFilter().filter(newText);
            MainActivity.this.arrayAdapter2.getFilter().filter(newText);
            return false;
        }
    });

和SearchView

 sr_txt.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            MainActivity.this.arrayAdapter.getFilter().filter(query);
            MainActivity.this.arrayAdapter2.getFilter().filter(query);
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            MainActivity.this.arrayAdapter.getFilter().filter(newText);
            MainActivity.this.arrayAdapter2.getFilter().filter(newText);
            return false;
        }
    });

但是我仍然面临着一个问题，当我搜索它从数组中搜索整个字符时，我需要一个解决方案如果我只能从它中搜索五个字符，它将会很好地工作。
