        public void onClick(View v) {
            autobtn.setImageResource(R.drawable.autoactive);
            SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(ModeActivity.this);
            SharedPreferences.Editor edit = sharedPreferences.edit();
            edit.putString("focus_value", "focus_mode_auto");
            Intent it = new Intent(ModeActivity.this, MainActivity.class);
            startActivity(it);
            edit.commit();
            //MainActivity.grid.setVisibility(View.VISIBLE);
        }
    });

在第二张专业照片中选择了

推荐答案

您可以像这样使用SharedPreferences.

You can use the SharedPreferences like this.

SharedPreferences sharedPreferences; 

sharedPreferences = PreferenceManager.getDefaultSharedPreferences(ModeActivity.this);
        SharedPreferences.Editor edit = sharedPreferences.edit();
        edit.putBoolean("focus_value", false);
        edit.putBoolean("auto_value", false); 
        edit.commit();

在您的按钮事件中，

autobtn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {

        boolean auto = edit.getBoolean("auto_value", false);
        boolean pro = edit.getBoolean("pro_value", false);

        if(!auto){
            edit.putBoolean("auto_value", true);
            autobtn.setImageResource(R.drawable.autoactive);
            edit.putBoolean("pro_value",false);
            probtn.setImageResource(R.drawable.xxxxx);
        }

        Intent it = new Intent(ModeActivity.this, MainActivity.class);
        startActivity(it);

    }
});
