如何在LinearLayout中单击另一个Textview时不显示所有TextView

Question

我试图在单击另一个textview（较小的一个）时打开打开相应的textview（较大的一个）之前隐藏任何已打开的TextView（较大的一个）

在打开TextView（Samller One）下相应的textview（BiggerOne）之前，我没有像下面那样执行打开的TextView（BiggerOne）程序。

我是Android新手，请帮助我解决此问题。

程序：

public class lessonOne extends AppCompatActivity {

    Toolbar toolbar;
    private CharSequence mTitle;
    LinearLayout linearLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_lesson_one);


        //Start a new Activity on clicking the TextView
        final TextView Engtxt = (TextView) findViewById(R.id.jan);
        Engtxt.setOnClickListener(new View.OnClickListener(){

            public void onClick(View v) {

                TextView txt = (TextView) findViewById(R.id.jan);
                //Define the map to iterate the visibility TextView
                Map<Integer, Boolean> map = new HashMap<Integer, Boolean>();
                map.put(v.getId(), FALSE);
                if (map.get(v.getId()) == FALSE) {

                    Engtxt.setVisibility(View.GONE);
                    TextView titleText = (TextView) findViewById(R.id.lesOneTitle);
                    titleText.setVisibility(View.GONE);
                    LinearLayout linearLayout = (LinearLayout) findViewById(R.id.linear);
                    linearLayout.setOrientation(LinearLayout.VERTICAL);
                    /* Add textview 1 */
                    TextView textView1 = new TextView(lessonOne.this);
                    //            textView1.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
                    //                    LinearLayout.LayoutParams.MATCH_PARENT));
                    LinearLayout.LayoutParams textviewLayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 200);
                    textviewLayoutParams.setMargins(0, 9, 0, 0);
                    //linearLayout.addView(textView1, 1, textviewLayoutParams);
                    textView1.setLayoutParams(textviewLayoutParams);
                    textView1.setBackgroundResource(R.drawable.shapelineinsideroundedrect);
                    textView1.setText("JANUARY - ஜனவரி\n\nजनवरी - JANUARY - ஜனவரி");
                    textView1.setGravity(Gravity.TOP | Gravity.CENTER);
                    textView1.setTextSize(20);
                    textView1.setTypeface(null, Typeface.BOLD);
                    textView1.setPadding(0, 25, 0, 0);
                    textView1.setVisibility(View.VISIBLE);
                    linearLayout.addView(textView1, 0);
                    //.setContentView(linearLayout, new LinearLayout.LayoutParams(
                    //LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
                    map.put(v.getId(),TRUE);
                }else {
                    TextView extendedText = (TextView) findViewById(v.getId());
                    extendedText.setVisibility(View.GONE);
                    map.put(v.getId(),FALSE);
                }
            }
        });

        //Call the Toolbar method to set and the getTitle method to be visible
        setupToolbar();
        mTitle = getTitle();

    }

    void setupToolbar(){
        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayShowHomeEnabled(true);
    }

    @Override
    public void setTitle(CharSequence title) {
        mTitle = title;
        getSupportActionBar().setTitle(mTitle);
    }
}
