今天第10天瞜:)
今天學習顯性intent和隱性intent
還有向下一個Activity發送數據

利用intent.setAction去呼叫手機裡的應用
例如:電話、簡訊等等

public class ActionUriActivity extends AppCompatActivity implements View.OnClickListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        EdgeToEdge.enable(this);
        setContentView(R.layout.activity_action_uri);
        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_dial).setOnClickListener(this);
        findViewById(R.id.btn_sms).setOnClickListener(this);
        findViewById(R.id.btn_my).setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        Intent intent = new Intent();
        String phoneNo = "55688";
        if(view.getId() == R.id.btn_dial){
            intent.setAction(intent.ACTION_DIAL);
            Uri uri = Uri.parse("tel:"+ phoneNo);
            intent.setData(uri);
            startActivity(intent);
        } else if (view.getId() == R.id.btn_sms) {
            intent.setAction(intent.ACTION_SENDTO);
            Uri uri = Uri.parse("smsto:"+ phoneNo);
            intent.setData(uri);
            startActivity(intent);
        }else if(view.getId() == R.id.btn_my){
            intent.setAction("android.intent.action.NING");
            intent.addCategory(intent.CATEGORY_DEFAULT);
            startActivity(intent);
        }
    }
}

寫兩個Activity來傳遞數據

public class ActSendActivity extends AppCompatActivity implements View.OnClickListener {

    private TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        EdgeToEdge.enable(this);
        setContentView(R.layout.activity_act_send);
        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_send).setOnClickListener(this);
        textView = findViewById(R.id.tv_send);
    }

    @Override
    public void onClick(View view) {
        Intent intent = new Intent(this, ActReceiveActivity.class);
        Bundle bundle = new Bundle();
        bundle.putString("現在時間", DateUtil.getNowTime());
        bundle.putString("天氣",textView.getText().toString());
        intent.putExtras(bundle);
        startActivity(intent);
    }
}

public class ActReceiveActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        EdgeToEdge.enable(this);
        setContentView(R.layout.activity_act_receive);
        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;
        });
        TextView textView = findViewById(R.id.tv_receive);
        Bundle bundle =  getIntent().getExtras();
        String time = bundle.getString("現在時間");
        String weather = bundle.getString("天氣");
        //textView.setText("現在時間"+time+"天氣"+weather);
        String desc = String.format("現在時間:%s\n天氣%s",time,weather);
        textView.setText(desc);

    }
}
