Android开发教程实战案例源码分享-点击五个星评分效果

有时用到对app评分功能，会用到五星好评

一、思路：

用5个ImageView，点击第几个进行处理

二、效果图：

三、关键代码：

class MainActivity : AppCompatActivity() {

    private lateinit var ivChatScoreStart1:ImageView
    private lateinit var ivChatScoreStart2:ImageView
    private lateinit var ivChatScoreStart3:ImageView
    private lateinit var ivChatScoreStart4:ImageView
    private lateinit var ivChatScoreStart5:ImageView
    private lateinit var tvChatScore:TextView


    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        ivChatScoreStart1 = findViewById(R.id.iv_chat_score_start1)
        ivChatScoreStart2 = findViewById(R.id.iv_chat_score_start2)
        ivChatScoreStart3 = findViewById(R.id.iv_chat_score_start3)
        ivChatScoreStart4 = findViewById(R.id.iv_chat_score_start4)
        ivChatScoreStart5 = findViewById(R.id.iv_chat_score_start5)
        tvChatScore = findViewById(R.id.tv_chat_score)

        ivChatScoreStart1.setOnClickListener {
            ivChatScoreStart1.isSelected = if (ivChatScoreStart2.isSelected){
                true
            } else {
                !ivChatScoreStart1.isSelected
            }
            if (ivChatScoreStart1.isSelected){
                tvChatScore.setText(R.string.chat_score_start_1)
            } else {
                tvChatScore.setText(R.string.chat_score_no_select_tip2)
            }
            ivChatScoreStart2.isSelected = false
            ivChatScoreStart3.isSelected = false
            ivChatScoreStart4.isSelected = false
            ivChatScoreStart5.isSelected = false
        }
        ivChatScoreStart2.setOnClickListener {
            ivChatScoreStart2.isSelected = if (ivChatScoreStart3.isSelected){
                true

            if (ivChatScoreStart2.isSelected){
                ivChatScoreStart1.isSelected = true
                tvChatScore.setText(R.string.chat_score_start_2)
            } else {
                tvChatScore.setText(R.string.chat_score_start_1)
            }
            ivChatScoreStart3.isSelected = false
            ivChatScoreStart4.isSelected = false
            ivChatScoreStart5.isSelected = false
        }
        ivChatScoreStart3.setOnClickListener {

            }
            ivChatScoreStart4.isSelected = false
            ivChatScoreStart5.isSelected = false
        }
        ivChatScoreStart4.setOnClickListener {

            ivChatScoreStart4.isSelected = if (ivChatScoreStart5.isSelected){
                true
