大家好，我想更改已选中的文本视图以切换首选项 我应该使用什么方法这是我检查的文本视图方法 我想做同样的事情，但有开关偏好

        ctv.setChecked(false);
    } else if (mysetting.service) {
        ctv.setChecked(true);

            if (ctv.isChecked()) {
                mysetting.service = false;
                ctv.setChecked(false);
                Editor editor = PreferenceManager.getDefaultSharedPreferences(MainActivity.this).edit();

Answer 1

强烈建议使用 setOnCheckedChangeListener 打开（选中）或关闭（取消选中），一旦这个视图是一个 CompoundButton (link)：

    switch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if(ischecked){
      //do something if is checked
    }else{
     //do something if is unchecked
    }
}

});

private boolean serviceEnable = false;

    public boolean isServiceEnable() {
        return serviceEnable;
    }

    public void setServiceEnable(boolean serviceEnable) {
        this.serviceEnable = serviceEnable;
    }

    private void savePreference() {
        SharedPreferences.Editor editor = PreferenceManager.getDefaultSharedPreferences(this).edit();
        editor.putBoolean("service", isServiceEnable());
        editor.commit();
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.checked_textview);

        final CheckedTextView cc = (CheckedTextView) findViewById(R.id.check_text_view);
        cc.setChecked(isServiceEnable());

        cc.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                setServiceEnable(!isServiceEnable());
                cc.setChecked(isServiceEnable());
                savePreference();
            }
        });
    }
