In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Go to the MainActivity.java code first. I use a timer here. I wanted to use java threads, but I don't know how to use Android yet, and the application will flicker.

Package com.example.myapplication; import androidx.appcompat.app.AppCompatActivity; import android.os.Bundle;import android.os.Handler;import android.view.View;import android.widget.Button;import android.widget.ImageView;import android.widget.TextView; import java.util.Random;public class MainActivity extends AppCompatActivity {private ImageView TP1, TP2, TP3; private Button BTN_START, BTN_FINISH; private TextView RESULT; private int [] img = {R.drawable.z1, R.drawable.z2, R.drawable.z3} Random a = new Random (); / / Random number int b, c, d; Handler handler= new Handler (); Runnable runnable=new Runnable () {@ Override public void run () {/ / TODO Auto-generated method stub / / what to do b = a.nextInt (3); c = a.nextInt (3) D = a.nextInt (3); TP1.setImageResource (IMG [b]); / / place random pictures TP2.setImageResource (IMG [c]); TP3.setImageResource (IMG [d]); handler.postDelayed (this, 20);}} @ Override protected void onCreate (Bundle savedInstanceState) {super.onCreate (savedInstanceState); setContentView (R.layout.activity_main); show (); BTN_START.setOnClickListener (new View.OnClickListener () {/ / start button listening event @ Override public void onClick (View view) {handler.postDelayed (runnable, 20) / / timer start}}); BTN_FINISH.setOnClickListener (new View.OnClickListener () {/ / end button listening event @ Override public void onClick (View view) {handler.removeCallbacks (runnable)) / / timer ends if (img [b] = = img [c] & & img [b] = = img [d] & img [c] = = img [d]) {if (IMG [b] = = img [0]) {RESULT.setText ("Congratulations on your character explosion, winning the first prize: three pea shooters") } else if (IMG [b] = = img [1]) {RESULT.setText ("Congratulations on your character explosion, winning the special prize: three corn pitchers");} else if (IMG [b] = = img [2]) {RESULT.setText ("Congratulations on the smoke from your ancestral grave and your diamond gift bag") }} else if (img [b] = = img [c]) {if (IMG [b] = = img [0]) {RESULT.setText ("Congratulations, second prize: two pea shooters") } if (IMG [b] = = img [1]) {RESULT.setText ("Congratulations, winning the second prize: 2 corn pitchers") } if (IMG [b] = = img [2]) {RESULT.setText ("Congratulations, second prize: two diamonds!") ;} else if (img [b] = = img [d]) {if (img [b] = = img [0]) {RESULT.setText ("Congratulations, second prize: two pea shooters") } if (img [b] = = img [1]) {RESULT.setText ("Congratulations, second prize: 2 corn pitchers") } if (img [b] = = img [2]) {RESULT.setText ("Congratulations, winning the second prize: two diamonds!") ;} else if (img [c] = = img [d]) {if (img [c] = = img [0]) {RESULT.setText ("Congratulations, second prize: two pea shooters") } if (img [c] = = img [1]) {RESULT.setText ("Congratulations, second prize: 2 corn pitchers") } if (img [c] = = img [2]) {RESULT.setText ("Congratulations, second prize: two diamonds!") ;}} else {RESULT.setText ("too bad luck! let's put a coin and do it again.") );} private void show () {TP1 = findViewById (R.id.tp1); TP2 = findViewById (R.id.tp2); TP3 = findViewById (R.id.tp3); BTN_START = findViewById (R.id.btn_start); BTN_FINISH = findViewById (R.id.btn_finish) RESULT = findViewById (R.id.result);}}

Place the layout in activity_main.xml.

The effect is as follows

End result: the video is too big

Attach a few pictures, click the start picture to switch constantly, and click the end button to judge the result.
