android - 如何检查我的编辑文本输入值是否等于数组值

Question

String[] zipcode = {"123","456"}如果匹配失败，我想检查我的编辑文本值是否等于数组值 toast success。

这是我的代码：

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final EditText et_zipcode = (EditText) findViewById(R.id.etzipcode);
        Button bt_submit = (Button) findViewById(R.id.btsave);

        bt_submit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String[] zipcodes = {"123","456"};
                if (et_zipcode.getText().equals(zipcodes)){
                    Toast.makeText(MainActivity.this, "Success", Toast.LENGTH_SHORT).show();
                }else {
                    Toast.makeText(MainActivity.this, "Failed", Toast.LENGTH_SHORT).show();
                }
            }
        });
    }
}

 button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            boolean isSuccess = true;
            String[] zipcodes = {"123", "456"};
            for (int i = 0; i < zipcodes.length; i++) {
                if (et_zipcode.getText().toString().equals(zipcodes[i])) {
                    isSuccess = false;
                    Toast.makeText(MainActivity.this, "Success", Toast.LENGTH_SHORT).show();
                }
            }
            if (isSuccess) {
                Toast.makeText(MainActivity.this, "Failed", Toast.LENGTH_SHORT).show();
            }
        }
    });
