Answer 1

您应该使用您评论过的代码：

Intent myIntent = new Intent(HomeActivity.this, Change_Password_Activity.class);
 startActivity(myIntent);

确保您要隐式化的活动的名称具有名称＆＃34; Change_Password_Activity ＆＃34;

Answer 2

试试这个：

@Override
    public boolean onOptionsItemSelected(MenuItem item) {

        int id = item.getItemId();

        switch(id){
            case R.id.changepwd:
     //                Intent myIntent = new Intent(HomeActivity.this, Change_Password_Activity.class);
     //                this.startActivity(myIntent);
                startActivity(new Intent("com.example.aishwarya.registerlogin.change_password_activity"));
            Toast.makeText(this, "You selected change pwd", Toast.LENGTH_SHORT).show();
                break;

            case R.id.setuname:
                Toast.makeText(getApplicationContext(), "You selected set username", Toast.LENGTH_SHORT).show();
                break;

            case R.id.setdp:
                Toast.makeText(getApplicationContext(), "You selected set profile picture", Toast.LENGTH_SHORT).show();
                break;

        }
        return true;

    }
