Android Intent调用 Uri的使用几种格式

打开百度

 Uri uri = Uri.parse("http://www.baidu.com");

 Intent intent =new Intent(Intent.ACTION_VIEW,uri);
 startActivity(intent);

打开另一个页面

Intent intent =new Intent(MainActivity.this,Main2Activity.class);
startActivity(intent);

 //拨打电话

Uri uri = Uri.parse("tel:10010");
Intent it = new Intent(Intent.ACTION_DIAL, uri);
startActivity(it);
//权限设置如下

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:andro >
        </activity>
    </application>

</manifest>

传达信息

Intent intent =new Intent(MainActivity.this,Main2Activity.class);

intent.putExtra("yl1","gisoracle");

//用Bundle携带数据
Bundle bundle=new Bundle();
//传递name参数为tinyphp
bundle.putString("yl2", "我爱你桂霞");
intent.putExtras(bundle);
startActivity(intent);

public class Main2Activity extends AppCompatActivity {

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);

    //获取Intent携带数据
    Intent intent = getIntent();
    String index = intent.getStringExtra("yl1");

    //用Bundle携带数据
    Bundle bundle = getIntent().getExtras();
    String data = bundle.getString("yl2");//读出数据

    Toast.makeText(this, index + "-" + data, Toast.LENGTH_SHORT).show();
}
