Question

我有main.xml包含一个按钮，tab.xml包含标签片段，是否有人知道如何通过按下main.xml中的按钮移动到标签活动？

Answer 1

activity_main.xml中：

<?xml version="1.0" encoding="utf-8"?>
    <android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.snehpandya.myapplication.MainActivity">

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"/>

</android.support.constraint.ConstraintLayout>

MainActivity.java：

public class MainActivity extends AppCompatActivity {

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

        Button mButton = (Button) findViewById(R.id.button1);
        mButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent mIntent = new Intent(MainActivity.this, NewActivity.class);
                startActivity(mIntent);
                finish();
            }
        });
    }
}

如何通过按主活动中的按钮转到标签活动？
