Question

我需要在每个动态生成的textview上添加一个click事件。

textview采用数组形式，我添加了从json字符串中提取的文本视图。

指导我如何实现它。

下面是我的代码：

    Button b =(Button) findViewById(R.id.start);
    b.setOnClickListener(this);
    starters = (TextView) findViewById(R.id.textView1);
    starters.setOnClickListener(this);

    tl = (TableLayout) findViewById(R.id.tablelayout1);
    rl = (RelativeLayout) findViewById(R.id.rel1);

    itemList = new ArrayList<HashMap<String, String>>();

    lv.setOnItemClickListener(new OnItemClickListener() {


        @Override
        public void onItemClick(AdapterView<?> parent, View view,int position, long id) {

        String name = ((TextView) view.findViewById(R.id.name)).getText().toString();

        Intent in = new Intent(getApplicationContext(),
        SingleContactActivity.class);

        in.putExtra(TAG_Name, name);

        startActivity(in);

        }
    });

    new Getitems().execute();
}

@Override
public void onClick(View arg0) {

    switch(arg0.getId()){

    case R.id.textView1: 
    ontextview1click();
    break;

    case R.id.start:
        try {
            onbuttonclick();
        } catch (JSONException e) {

            e.printStackTrace();
        }
        break;

    }
}

private void onbuttonclick() throws JSONException {
    TableRow[] tr = new TableRow[items.length()];
    TextView[] tx = new TextView[items.length()];

    TableLayout tl = (TableLayout) findViewById(R.id.tablelayout1);
    for (int i = 0; i < items.length(); i++) {
        JSONObject c = items.getJSONObject(i);

        String category = c.getString(TAG_Cat);
        tx[i] = new TextView(S1.this);
        tx[i].setLayoutParams(new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
        tx[i].setText(category);

        tr[i] = new TableRow(S1.this);
        tr[i].setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
        tr[i].addView(tx[i],new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
        tl.addView(tr[i],new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
    }
}

private void ontextview1click() {

    if (key==0){
        key=1;
        lv.setVisibility(View.VISIBLE);
               }

        else if(key==1) {
        key=0;
        lv.setVisibility(View.GONE);
        }
}

Answer 1

tx[i].setOnClickListener(this);

然后点击方法

public void onClick(View arg0) {


        if(arg0==tx[i]){

        }
}

如何在android中为每个动态生成的textview数组添加点击监听器？
