Question

我的代码是我写的：

while (i.hasNext()){
        Map.Entry me= (Map.Entry) i.next();
        checkBox=new CheckBox(this.getActivity());
        checkBox.setId(Integer.parseInt(me.getKey().toString()));
        checkBox.setText(me.getValue().toString());
        checkBox.setOnClickListener(getOnClickDoSomething(checkBox));
        LinearLayout.LayoutParams params= (LinearLayout.LayoutParams) linearMain.getLayoutParams();
        params.width=250;
        linearMain.addView(checkBox);
        dltButton=new Button(this.getActivity());
        dltButton.setTag(btnCounter);
        btnCounter++;
        dltButton.setText("Delete");
        linearMain.addView(dltButton);


    }

屏幕就像这样。

我想要一个复选框和一个删除按钮，并且下一行中的下一行类似。如何实现它？

Answer 1

好吧试试这个，我已经将你的代码修改为基本逻辑。你的活动布局文件应如下所示

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
</LinearLayout >

然后你的活动应该是

     public class MainActivity extends AppCompatActivity {

LinearLayout mainContainer;

CheckBox checkBox;
Button dltButton;

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

    mainContainer = (LinearLayout) findViewById(R.id.mainContainer);

    for (int i = 0; i < 5 ; i++){

        checkBox=new CheckBox(this);
        checkBox.setText("Text");

        LinearLayout linearMain = new LinearLayout(this);
        linearMain.setOrientation(LinearLayout.HORIZONTAL);
        linearMain.setWeightSum(1.0f);

        LinearLayout.LayoutParams half = new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.WRAP_CONTENT,
                LinearLayout.LayoutParams.WRAP_CONTENT, 0.5f);

        linearMain.addView(checkBox, half);

        dltButton=new Button(this);
        dltButton.setTag("tag");
        dltButton.setText("ffff");
        linearMain.addView(dltButton, half);

        mainContainer.addView(linearMain);



    }

}

Answer 2

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

    LinearLayout layout = (LinearLayout) findViewById(R.id.linear_layout);
    layout.setOrientation(LinearLayout.VERTICAL);
    String[] count = new String[] { "1", "2", "3" };

    int checkbox_count = 3;
    CheckBox checkBox;

    for (int i = 0; i < checkbox_count; i++) {
        LinearLayout horizontal_layout = new LinearLayout(this);
        horizontal_layout.setOrientation(LinearLayout.HORIZONTAL);
        horizontal_layout.setLayoutParams(new LinearLayout.LayoutParams(500, 80));
        checkBox = new CheckBox(this);
        checkBox.setText("checkbox " + count[i]);
        horizontal_layout.addView(checkBox);
        Button delete_btn = new Button(this);
        delete_btn.setText("Delete");
        horizontal_layout.addView(delete_btn);
        layout.addView(horizontal_layout);
    }
}

如何在Android中并排放置线性布局中的复选框和按钮？
