TextView SpannableString属性详情

我们经常性的使用SpannableString属性,这个属性其实是很赞的.
这里实现了点击TextView跳转Activity.
Main3Activity代码

public class Main3Activity extends AppCompatActivity {
    private TextView content;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main3);
        //寻找组件
        content = findViewById(R.id.content);
        String text1 = "#参与话题我们都热爱学习#赢取百万大礼包";
        // 主要是用来拆分字符串
        SpannableString spannableString = new SpannableString(text1);
        spannableString.setSpan(new ClickableSpan() {

            @Override
            public void onClick(View widget) {

                Intent intent = new Intent(Main3Activity.this, Main4Activity.class);
                startActivity(intent);
            }
        }, 0, 12, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);  //SPAN_EXCLUSIVE_EXCLUSIVE从字符串0-text1.length任意位置触发点击事件
        content.setText(spannableString);
        content.setMovementMethod(LinkMovementMethod.getInstance());

    }
}
