java - 如何通过单击添加按钮将数据从一个 Activity 移动到下一个 Activity (ListView)？

Question

我正在创建一个健身应用程序，允许用户创建自己的锻炼列表，他们可以通过单击 ImageView 旁边的“+”按钮来完成此操作。单击一下，imageview、textview1 和 textview2 应添加到下一个 Activity 的 ListView 中。基本上，当单击按钮时，数据应该添加到具有 ListView 的 UserCustomiseWorkout

AllExercise Java

public class AllExercises extends AppCompatActivity {

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

    ImageButton imagebutton7 = (ImageButton) findViewById(R.id.imageButton7);
    imagebutton7.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(getApplicationContext(), UserCustomiseWorkout.class);
            startActivity(intent);
        }
    });
}


public void clickNextExPage(View v)
{
    Intent nextpage = new Intent(this, AllExercises2.class);
    startActivity(nextpage);
}

Answer 1

获取文本 从 TextView 中，创建一个列表，将它们添加到列表中，通过意图将列表传递到下一个 Activity ，从意图中获取列表。这是解决您的问题的简单方法。但也许为了更好的方法，您希望将此项目添加到数据库并在需要时获取它们。
