每日一篇学习笔记 直到我做完专题 :( [Day17]

今天学习系统的提醒对话框

利用系统对话框来选择显示甚么讯息

public class AlertDialogActivity extends AppCompatActivity implements View.OnClickListener {

private TextView tv_alert;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
EdgeToEdge.enable(this);
setContentView(R.layout.activity_alert_dialog);
ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main), (v, insets) -> {
Insets systemBars = insets.getInsets(WindowInsetsCompat.Type.systemBars());
v.setPadding(systemBars.left, systemBars.top, systemBars.right, systemBars.bottom);
return insets;
});

findViewById(R.id.btn_alert).setOnClickListener(this);
tv_alert = findViewById(R.id.tv_alert);
}

@Override
public void onClick(View view) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("亲爱的用户");
builder.setMessage("你真的要卸载吗?");
builder.setPositiveButton("确定卸载", (dialogInterface, i) -> {
tv_alert.setText("谢谢您的配伴，后会有期");
});
builder.setNegativeButton("取消卸载", (dialogInterface, i) -> {
tv_alert.setText("我会持续提升自己的");
});

AlertDialog alertDialog = builder.create();
alertDialog.show();
}
}
