按钮在列表视图中不起作用

Question

这是主要的活动，其中一个列表视图有一些数据和一个按钮

它是显示数据，但是每当我单击该按钮时，它都不起作用。

final String [] from = new String[]{AllDB.COLUMN_NAME, AllDB.COLUMN_AGE, AllDB.COLUMN_HEIGHT , AllDB.COLUMN_WEIGHT};
final int [] to = new int[]{R.id.nameTV,R.id.ageTV,R.id.heightTV,R.id.weightTV};


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

    dBmanegar = new AllDBmanegar(this);
    dBmanegar.open();
    final Cursor cursor = dBmanegar.fetch();

    listView = (ListView) findViewById(R.id.list_view);
    listView.setEmptyView(findViewById(R.id.emptyTV));

    adapter = new SimpleCursorAdapter(this, R.layout.show_person_info, cursor, from, to,0);
    listView.setAdapter(adapter);
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            //TextView idTextView = (TextView)view.findViewById(R.id.idTV);
            TextView nameTextView = (TextView) view.findViewById(R.id.nameTV);
            TextView ageTextView = (TextView) view.findViewById(R.id.ageTV);
            TextView heightTextView = (TextView) view.findViewById(R.id.heightTV);
            TextView weightTextView = (TextView) view.findViewById(R.id.weightTV);
            Button diet = (Button) view.findViewById(R.id.diet);
            diet.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Intent diet_P = new Intent(getApplicationContext(), Diet.class);
                    startActivity(diet_P);
                }
            });

            //String iD = idTextView.getText().toString();
            String name = nameTextView.getText().toString();
            String age = ageTextView.getText().toString();
            String height = heightTextView.getText().toString();
            String weight = weightTextView.getText().toString();

            Cursor cursor1 = (Cursor) parent.getItemAtPosition(position);
            cursor1.moveToFirst();
            //iD = cursor1.getString(cursor1.getColumnIndex(MyDB.COLUMN_ID));



            Intent intent = new Intent(getApplicationContext(), Modify_person_info.class);
            //intent.putExtra("_id",iD);
            intent.putExtra("name", name);
            intent.putExtra("age", age);
            intent.putExtra("height", height);
            intent.putExtra("weight", weight);

            startActivity(intent);


        }
    });



}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.add_person,menu);
    return true;
}


public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    if(id == R.id.add_person){
        Intent intent = new Intent(this,Add_new.class);
        startActivity(intent);

    }else if (id == R.id.laout){
        Intent backToHome = new Intent(this,MainActivity.class);
        startActivity(backToHome);
        finish();
    }

    return super.onOptionsItemSelected(item);
}

这是 SimpleCursorAdapter 的 XML，用于显示数据和按钮

Answer 1

尝试将以下属性从 XML 添加到 Button：

android:focusable="false"

如果不起作用，请为 listview 创建一个自定义适配器： Custom Adapter for List View
