1.匿名內部類

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn1 = findViewById(R.id.btn1);//匿名內部類
btn1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(),“你點選了按鈕1”,Toast.LENGTH_LONG).show();
}
});
}

2.內部類

public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn2 = findViewById(R.id.btn2);
Btn2CLickListener btn2CLickListener = new Btn2CLickListener();
btn2.setOnClickListener(btn2CLickListener);
}
class Btn2CLickListener implements View.OnClickListener{
@Override
public void onClick(View v){
Toast.makeText(getApplicationContext(),“你點選了按鈕2”,Toast.LENGTH_LONG).show();
}
}

3外部類**

MainActivity.java：

public class MainActivity extends AppCompatActivity{
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
Button btn3 = findViewById(R.id.btn3);
Btn3ClickListener btn3CLickListener = new Btn3ClickListener(getApplicationContext());
btn3.setOnClickListener(btn3CLickListener);
}

Btn3ClickListener.java：

4自身activity

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn4 = findViewById(R.id.btn4);//main activity
btn4.setOnClickListener(this);
}

public void onClick(View v) {
Toast.makeText(getApplicationContext(),“你點選了按鈕4”,Toast.LENGTH_SHORT).show();
}
}

5直接繫結到標籤

activity_main.xml：

新增 android:onClick=“myClick”。如下所示：

MainActivity.java：

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
public void myClick(View view) {
Toast.makeText(getApplicationContext(),“你點選了按鈕5”,Toast.LENGTH_SHORT).show();
}
}
